Strength – Both concrete blocks and bricks are relatively strong, but the efficacy of this strength is helped and/or hindered by the quality of the mortar that is used to hold them together in construction. Concrete blocks must have a minimum compressive strength of 1,900lbs per square inch, but many blocks’ strength vastly exceeds this limit.

Why concrete blocks are better than bricks?
While clay bricks are commonly used in construction, concrete blocks can help you save money while building your home. Clay bricks are 2 ½ to 3 times stronger than the concrete bricks. It is important to note that the strength of a brick wall depends on the quality of the mortar holding the blocks together. Here are four reasons why you should consider concrete blocks over bricks. Concrete blocks use lesser jointing material due to their larger size. With a more regular shape, they require lesser plastering material, They absorb less water than bricks, thus reducing dampness in the walls. They are economically more feasible.

Advantages of Bricks –
Heat Protection in SummerBricks have a higher thermal mass than AAC blocks, which allows them to absorb more heat. During the day, the bricks absorb heat and release it at night. In essence, you have the finest possible option for keeping your home warm in the winter and cool in the summer.Days typically require less heat than nights, which is when bricks’ thermal insulation abilities come into play. Bricks are especially useful in the terai region of Nepal, where the climate is hot and the houses need heat absorption to keep cool.Eco-friendlyThose of you who condemn the environmental issues of manufacturing red bricks entirely forget that these bricks are manufactured from materials that can be readily recycled and utilized for landfills. Blocks, on the other hand, are a different story.Because they are made of concrete, they are not as recyclable as bricks. All of the renovation work that necessitates the demolition of old structures in order to construct new ones would result in mountains of waste that could not be recycled.DurabilityTraditional red bricks are believed to be more durable, and constructions built with them are stronger than hollow block structures. The durability of blocks is also said to last only if they are well maintained, as opposed to bricks, which can stand stiff for years if the construction is done in accordance with the proper methods.FireproofBricks are made up of Earthen materials that have been highly compressed. Because of the extreme compression, there is very little area for combustion to ignite and spread. They have the highest fire safety rating. They can withstand a large, well-developed fire significantly better than a house made of blocks or other materials.Free of Maintenance Masonry bricks require almost no upkeep.They don’t require as much care once they’re built as block constructions do from time to time. They have no long-term maintenance costs, whereas block constructions must be maintained after a few years or they may begin to fall apart in areas.
The brick vs. block debate is a tight one, and anyone planning to undertake a construction project will have to weigh the advantages and disadvantages of both. However, a lot relies on the builder’s location,, and situation. Some people prefer brick masonry projects because they want less upkeep in the long run, even if the cost of construction is more.
What’s harder than a brick?
How Does Steel Stand Up To Brick? – While there’s no doubt that brick is a sturdy material, steel is one of the strongest and longest-lasting construction materials you can use. When you’re looking at steel vs. brick, steel holds up very well when it comes to regular wear and tear and also stands up against extreme weather like strong winds, heavy snow, and ice.
Steel is also pest and fire-resistant. Need to move? Steel is not likely to break or warp when it’s being taken down or moved, and can typically be used again in a new location or even recycled. In comparison, brick is pretty much impossible to move without major reconstruction work. Over time brick can deteriorate or even crumble in the event of an accident or direct impact.
Brick can also be susceptible to extreme weather, and in some cases, brick can require regular maintenance. Steel buildings require little to no maintenance and can stand up in the face of bad weather and even regular wear and tear. Choosing steel can save you money over time because you won’t have to spend as much for regular maintenance, repairs and general upkeep.

What are the disadvantages of concrete blocks?
A Concrete Block is a ‘Building Block’ composed entirely of concrete that is then mortared together to make an imposing, long-lasting construction. These construction blocks can be ‘Hollow’ or ‘Solid,’ formed of ordinary or lightweight concrete in various specified sizes, depending on the precise requirements.
- Concrete blocks come in various shapes and sizes, and they can be solid or hollow.39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, 10 inch, and 12-inch unit configurations are the most popular concrete block sizes.
- Concrete blocks are made from cement, aggregate, and water.
- In concrete blocks, the cement-aggregate ratio is 1:6.
Types of Concrete Blocks: There are two types of concrete blocks: 1. Solid Concrete Blocks 2. Hollow Concrete Blocks 1. Solid Concrete Blocks: Fig 1: Solid Concrete Blocks Courtesy: homedepot.com Solid concrete blocks, which are highly heavyweight and formed by aggregate, are primarily utilized in construction projects. They’re sturdy and give structures a lot of solidities. These solid blocks are ideal for large-scale projects such as force-bearing walls. Fig 2: Hollow Concrete Blocks Courtesy: cementconcrete.org In masonry construction, hollow concrete blocks are typically employed. It reduces labour costs on the job site while also speeding up the construction process and saving cement and steel. These blocks reduce the natural weight of masonry structures while also improving physical wall qualities like noise and thermal insulation.
Standard hollow concrete blocks come in two sizes: Full size and half size. Half-sized blocks are cubical and have one core, while full-sized blocks are rectangular and have two cores. The nominal size of concrete blocks, according to the ‘Research Designs & Standards Organization of Indian Railways,’ is as follows: i) 400, 500, or 600 mm in length ii) 200 or 100 mm in height iii) 50, 75, 100, 150, 200, 250, or 300 mm in width.
Hollow concrete blocks come in various shapes, sizes, and designs, depending on the shape, needs, and design.1. Concrete Stretcher Blocks: Concrete stretcher blocks are also employed at the masonry’s corners. Concrete stretcher blocks commonly use hollow concrete blocks. Fig 3: Concrete Stretcher Blocks Courtesy: homestratosphere.com 2. Concrete Corner Blocks: Fig 4: Concrete Corner Blocks Courtesy: rcpblocks.com Concrete corner blocks are utilized at the masonry’s corners and the ends of windows and doors. One block corner is plain, while the other has a stretcher design. Concrete corner blocks are placed so that one end of the plane is exposed to the exterior and secured with the stretcher block.3. Lintel Blocks: Fig 5: Lintel Blocks Courtesy: oneontablock.com Lintel blocks are joined together to form lintel beams. These beams provide structural support by distributing loads from above the beam to the walls on both entry sides. They’re also prefabricated and made of pre-stressed concrete.4. Concrete Pillar Blocks: Fig 6: Concrete Pillar Blocks Courtesy: familyhandyman.com Since both corners are plain, concrete pillar blocks are also known as double corner blocks. As a result, they’re commonly employed when two corners are visible. As the name implies, concrete pillar blocks are commonly used in pillars and piers.5. Partition Concrete Blocks Fig 7: Concrete Pillar Blocks Courtesy: civilprojectsonline.com Partition concrete blocks are similar to concrete pillar blocks, except that the height of a partition concrete block, also known as a partition block, is more than the breadth. A partition block’s hollow section is separated into two or three parts. These blocks are perfect for building partition walls.6. Jamb Concrete Blocks: Fig 8: Jamb Concrete Blocks Courtesy: teknopanel.com When an intricate window opening in the wall, jamb blocks are employed. Stretcher and corner blocks are attached to them. Jamb blocks are very important for providing space for the window casing parts when installing double-hung windows.7. Bullnose Concrete Block: Fig 9: Bullnose Concrete Blocks Courtesy: jonesandsons.com Concrete pillar blocks and bullnose concrete blocks are the same things. The main distinction between the two types of concrete blocks is that a bullnose block has rounded corners, while a concrete pillar block does not. Bullnose concrete blocks may be the ideal choice for you if you desire rounded edges.8. Frogged Brick Blocks: Fig 10: Frogged Brick Blocks Courtesy: quizlet.com The top surface of this sort of block has a frog section and a header and stretcher. Frog aids in the retention of mortar and forming a strong bond with another brick.9. Paving Blocks: Fig 11: Paving Blocks Courtesy: homedepot.com Paving blocks are reinforced concrete boxes that are square or rectangular. Paving blocks are decorative concrete blocks used as a decorative approach for producing pavements. Paving blocks are commonly used in road construction, but they can also build car parks and walkways.
Paving blocks must be painted with high-visibility paints when used for road shoulders and paving so that drivers and motorists can see them.10. Light Aerated Concrete Blocks: The nature of light aerated concrete blocks is that they are light. These blocks are made of Portland cement, aggregates, high-quality sand, and other materials.
As a result, aerated concrete is used to make them.11. Fly Ash Blocks: Fig 12: Fly Ash Blocks Courtesy: buildwithash.com Fly ash blocks are lighter than clay bricks and are also more cost-effective. They are commonly made from waste products resulting from coal combustion in thermal power plants.12. Cellular Lightweight Concrete Blocks: The feature of cellular lightweight concrete blocks is that they are lightweight. Fig 13: Concrete Bricks Courtesy: wikihow.com Concrete bricks are small rectangular symmetric blocks that create a rigid wall. These bricks have greater compressive strength than normal clay bricks and have less water absorption property than clay bricks.
Concrete Blocks are a great option for partition walls because they are quick and easy to install. The inclusion of steel reinforcement adds to the structure’s strength. Exterior and Interior Load-bearing Walls, Partition Walls, Panel Walls, and Boundary Walls are common uses for Hollow Concrete Blocks. Solid Concrete Blocks are perfect for Chimney and Fireplace building, but they also work well for Non-load Bearing Walls and Garden Walls. Concrete blocks are also used in a variety of smaller landscaping projects. Many Outdoor Furniture & Patio ideas, for example, include Outdoor Seating, Decorative screens, Outdoor Bar, Flower Bed, and many others. Concrete blocks can cover stored commodities from the effects of changing weather. It’s no surprise that engineers prefer it to construct Material Bins.
Advantages of Concrete Blocks:
The reduced wall thickness due to narrower Concrete Blocks than a traditional brick masonry wall makes the space is larger by increasing the carpet surface. Concrete block building is more systematic, faster, and stronger than brick masonry because of the vast size of the blocks. Better thermal insulation is provided. It effectively absorbs sound and protects the interiors from noise pollution. Using concrete blocks provides additional fire protection. Protects precious agricultural land that is extensively mined to produce clay bricks. Individual pieces can be manufactured to a larger customized size and shape, allowing for a quick building cycle turnaround. Concrete Blocks, unlike traditional bricks, have a consistent size that lowers the need for plaster, making them a more cost-effective solution. The mortar consumption rate is lower than in traditional masonry construction, but the overall strength of the structure is increased.
Disadvantages of Concrete Blocks:
The expense of constructing a residence out of concrete blocks is significantly higher. Some of the blocks may need to be cut to reach critical systems. Concrete block homes aren’t usually attractive from the outside. Over time, concrete blocks may be subject to water seepage. Some regional preferences may not be compatible with this material. Windows and doors can easily detract from the environmental benefits.
Conclusion: When it comes to living arrangements, concrete block homes make sense if you want to be environmentally conscious. Although the cost of building is higher with this material, most homeowners can recoup the difference in cost throughout the life of the property when compared to timber frames.

Which is better red bricks or concrete blocks?
Why use concrete blocks for construction? –
Cheaper option: As compared to brick masonry, block masonry is much less expensive. They are known to cost Rs.1,500 less per cubic meter than brick masonry. This is not an insignificant distinction. According to estimates, the cost of constructing a wall out of AAC blocks is 17.65% less than the cost of constructing a wall out of conventional bricks. Better eco-friendly alternative: They do not affect or deplete nature in any way in the process of their production or manufacturing. They’re made of Fly Ash, which is a waste product from thermal power plants. Red bricks, on the other hand, absorb topsoil in their processing and manufacturing, depriving nature of its valuable protective layer of soil. That is the primary explanation for the National Green Tribunal’s opposition to red bricks. Soundproofing quality: Soundproofing may be a blessing for those who live in industrial areas or along busy roads. As opposed to brick constructions, block walls have a higher density and therefore have greater soundproofing. If your home is constantly surrounded by noise that prevents you from having a good night’s sleep, their powerful acoustic insulation is a huge help. Lighter weight: As compared to red bricks, concrete blocks are lighter, allowing for greater workability, stability, and durability. Their dry density ratio lowers the dead load on buildings, making them more functional and ideal for modern structures. Better strength: Concrete blocks are considered to be more resistant to earthquakes, hurricanes, and tornadoes, all of which are becoming more common these days. Countries that facilitate and encourage the use of blocks put a high priority on their resilience in the face of natural disasters. The way they’re built adds to their durability and strength. Space-saving: Concrete blocks are often recommended by builders and contractors because they save a significant amount of space overall. The width is reduced, but the reliability is not compromised, increasing the amount of space needed in the construction of walls. The traditional brick walls are being phased out, particularly in big cities where there is a lot of competition for space.
When it comes to choosing between concrete block and burnt brick, it’s a toss-up. Anyone who is about to begin building must consider the advantages and disadvantages of both concrete blocks and burnt brick. However, a lot is dependent on the budget, the builder’s situation, and the available space.
- If you want a one-time investment and want to avoid a lot of maintenance, then going for burnt bricks would be right for you.
- However, the production of burnt bricks is not eco-friendly.
- While concrete bricks are cheaper, the waste from them is non-recyclable.
- All in all, you have to keep in mind all the points and weigh which option suits better to your construction needs.

Does brick last longer than concrete?
Durable – Brick exteriors are able to withstand natural elements like water, rain, great wind speeds, and flying debris better than wood. They are also noncombustible which can help contain a fire to a particular room until it is put out, quite different from wood materials that easily catch fire.
- Insurers charge less for brick buildings due to their durability and the noncombustible nature of the materials.
- A brick home lasts longer than concrete and is more durable than wood.
- While wood has many benefits, it is not as reliable as using brick.
- Wood has a tendency of attracting different types of pests and may require treatment.
Termites or other insects are not a threat to brick or concrete. Mold can also affect wood, causing extensive damage leading to unnecessary repairs. If you like the look of climbing ivy, keep in mind that it may look pretty but is damaging to both brick and wood.
Which is cheaper concrete blocks or bricks?
Which One Cost More? – The cost of clay bricks and concrete blocks are pretty comparable – and tend to vary by as little as 20 cents a block, with clay brick typically on the higher side. Although, if you opt for specialty blocks, for instance lightweight blocks, costs can go up considerably, by a couple dollars per block.

Can a human break a brick?
How to Turn Your Fist Into a Block-Breaking Machine Few things in life offer more visceral proof of the power of physics than a karate chop. Punch a brick with your bare hand, and if you are untutored in the martial arts, you may break a finger. Punch it with the proper force, momentum, and positioning, and you’ll break the brick instead.
Amazingly, there are no tricks involved,” says Michael Feld, a physicist at MIT. “What you have here is one of the most efficient human movements ever conceived.” In the late 1970s, when Feld was earning a brown belt in karate, his instructor,, also happened to be his physics student. (McNair died in 1986 while working as a scientist-astronaut aboard the space shuttle Challenger.) The secret to karate, both men agreed, lies in the speed and focus of the strike.
But just how fast does a karate punch move? To find out, they joined with undergraduate Stephen Wilk and set up a strobe light that flashed either 60 or 120 times per second. Then they photographed McNair and others throwing kicks and punches and counted how many times the strobe flashed until the foot or fist hit its target.
Feld and McNair found that beginning students can throw a karate chop at about 20 feet per second, just enough to break a one-inch board. But like McNair could chop at 46 feet per second. Hitting a piece of wood at that speed, a 11/2-pound hand can deliver a wallop of up to 2,800 newtons (one newton is roughly equal to the force exerted by the weight of an apple).
Splitting a typical concrete slab 11/2 inches thick actually takes less, about 1,900 newtons. Of course, brute strength is not the only requirement for breaking concrete blocks — the nature of the chop is also important. Karate students must learn that for a strike to have maximum momentum, it must have a follow-through; golf and tennis players follow through with their swings for the same reason.
- To understand how follow-through works, Jearl Walker, a former tae kwon do student who now teaches physics at Cleveland State University, set up a study much like Feld’s and McNair’s.
- A well-thrown fist, he found, reaches its maximum velocity when the arm is about 80 percent extended.
- That’s exactly what my master had taught me,” Walker says.
“You focus your punch in your imagination so that it terminates inside your opponent’s body, rather than on the surface. To deliver the maximum power, you want to make contact before the slowdown begins.” What happens after contact is also very important.
All materials are at least slightly elastic: Whack them in the right spot and they will start to oscillate. “If you tweak a rubber band it goes up and down, and the same is true if you tweak a board or a brick with a much greater force,” Feld says. “When they reach, they start to yield. In other words, they break.” Fortunately for us, reaching the equivalent limit in the body’s bones is no easy matter.
Feld says bone can withstand 40 times as much force as concrete, and a cylinder of bone less than an inch in diameter and 21/3 inches long can withstand a force of 25,000 newtons. Hands and feet can take even more abuse, because skin, muscles, ligaments, tendons, and cartilage absorb a great deal of impact.
A well-kicked foot can absorb about 2,000 times as much force as concrete before breaking. Feld has never fractured a finger in karate, even though he once broke eight one-inch-thick boards at a time. If students want to break boards, they have to not only increase their speed and improve their aim but also toughen up their hands and feet by striking them against a post wrapped in foam and canvas.
“In the beginning, your skin is so soft you may end up cutting it. And then comes the blood,” says, a tae kwon do grandmaster. “This is not recommended.” Over time, the shuto, or knife-edge of the hand, develops a callus that acts exactly like a car bumper, absorbing and diffusing the force of a collision.
Are bricks as strong as concrete?
Masonry Blocks VS Bricks – Wednesday, May 29, 2019, posted by Baines Masonry Masonry blocks and bricks share some factors including their fire resistant properties, their high thermal mass and low insulation values. While Masonry blocks and bricks share these similarities, learning the difference between each can help you make an informed decision on what product to use in your next project.1.Insulation – Masonry blocks have a higher insulation level, with bricks being that similar to wood-framed buildings.2.
- Strength – While the strength of a wall can be dependent on the type of mortar used.
- In general, concrete blocks have a slightly higher level of strength than clay bricks, making them a stronger choice.3.Cost – While the cost of the individual block or brick may be similar, it is the labour and technical skill needed that may influence costs.
The larger size of the concrete masonry block may reduce the time needed to kay the blocks, thus reducing the costs associated with labour.4.Weight – Masonry block and brick are both quite heavy materials. Their individual weight depends on the materials and type of construction.
Can concrete blocks be load bearing?
Concrete blocks shall be capable of supporting intended loads, have appropriate thermal resistance and be resistant to the adverse effects of climate. Issues to be taken into account include: –
- intended loads
- freeze/thaw and sulfate attack
- other characteristics.
Is a brick wall stronger than a concrete block wall?
Strength – As stated, both and clay brick are pretty tough materials. Take a walk through almost any town in the US and you’ll see at least a dozen buildings made of each of these materials. The average concrete block can withstand 3500 psi (pounds per square inch) while a conventional clay brick can take 3000 psi.
Is brick or block better?
The differences between bricks and solid concrete blocks – Bricks and concrete blocks are made from different raw materials, meaning they have different structural compositions. Brick is made up of sand, lime and concrete materials, while concrete blocks are produced from aggregate consisting of crushed sand or stone.
- Concrete blocks have a much higher water resistance than bricks, and their compressive strength is higher.
- Concrete has a shorter life than brick, though it still gives efficient results for up to 100 years.
- It is also incredible durable and can be painted more easily than brick, which secretes metallic salts that can cause paint to peel off.
One of the main advantages of solid concrete blocks is that they offer outstanding fire resistance and the very highest fire safety rating. They’re often favoured for their thermal efficiency and sound insulation.
Are concrete blocks bulletproof?
Exterior Bullet Proof Walls – Fortunately, most commercial building materials used in exterior walls inherently offer decent bullet resistance. Poured concrete, cinderblock, and even lowly red-brick veneer will, for all practical purposes, stop any common domestic bullet.
“These aren’t bullet proof walls,” Total Security Solutions vice president Jim Richards warns, “but there’s enough material there to slow down bullets and keep them from popping through.” Unfortunately, commercial builders are increasingly turning to exterior insulation finishing system (or EIFS) for their exteriors.
While these finishes often look like concrete–or even granite–they are actually made of a layer of thick polystyrene foam (akin to the styrofoam used for take-away coffee cups and carry-out boxes) covered in nylon mesh coated in a thin layer of concrete-like finish.
What are the advantages of using blocks over bricks?
Conclusion about this material – Concrete is a material that has been used for construction since the late 1800s. It is made from a mixture of sand, gravel, and water that is mixed with cement. The cement sets after a few hours and hardens into a solid mass.
This process occurs in three stages: hydration, hydration-setting, and setting. The advantages of concrete blocks over bricks include durability as concrete blocks are harder to crack or break than bricks, maintenance because it’s easier to clean up concrete, and cost because there are fewer materials required to make concrete blocks than bricks.
: What are the advantages of concrete blocks over bricks?
Why did they stop making cinder blocks?
The standard construction block is often referred to as a cinder block or a CMU (Concrete Masonry Unit), but are they referencing the same thing? These three terms tend to be used interchangeably when talking about the modern-day grey block used for constructing walls and in recent years, some popular DIY projects.
But, we’re here to set the record straight and define the true difference between cinder block vs. construction block, and what CMU even means. In a few short minutes, you’ll be able to sound like a concrete block expert and have a few fun facts to tell your friends at your next outdoor gathering. CINDER BLOCKS Did you know that cinder blocks aren’t even made anymore? That’s right! They haven’t been manufactured since 1947 after WWII.
Then why is this name for a block still being used today? Well you can thank a man named Francis Straub for that. In early 1900’s coal fired plants created a byproduct called cinder. Francis Straub, discovered that these cinders were cementitious, or had the property of cement.
He started adding cinder and reducing the amount of cement in his concrete block mix, until he finally patented his material mix for the cinder block. Many others made their own versions, but his combination was insulated (resistance to conductive heat flow), light weight, and versatile enough that a nail could pierce through it and hold.
These cinder blocks were a great way to recycle the coal waste that used to be dumped around growing cities. This recycling also helped add strength to concrete blocks while reducing cost. The production of cinder blocks revolutionized the concrete block industry and the name cinder block was popularized and stuck long after the blocks were being made.
- CONSTRUCTION BLOCKS After WWII, better technology and production habits put an end to the production of cinder.
- Now, manufactures use the byproducts called fly ash and slag made from coal and steel to make these blocks.
- These are much safer than cinder and incorporating them in to block minimizes the carbon impact today.
Since the modern-day construction blocks don’t use cinder, we can’t really call these cinder blocks anymore so, what do we call them? The simple answer is construction block; It’s easy to remember and makes a lot of sense, as they are used for construction.
- CONCRETE MASONRY UNITS (CMUs) The typically DIYer might not hear this term a lot, but engineers, manufacturers, and American Society for Testing Materials (ASTM) will use the term CMU when referring to the construction block.
- This is the most technical term for this block.
- When the United States standardized the concrete block to specific dimensions, like 8-by-8-by-16, they had to account for the thickness of the mortar joint.
This is where the term concrete masonry units come from. So, when you buy a CMU or construction block listed by the nominal dimension of 8″ x 8″ x 16″, the actual dimension of the concrete block is smaller, at 7-5/8″ x 7-5/8″ x 15-5/8″ to make room for the mortar. In the end, whether you’re building a DIY backyard project or a house, the name doesn’t matter. Kind of like what Shakespeare wrote: “What’s in a name? That which we call a concrete block. By any other name would be just as strong.” Okay maybe Shakespeare didn’t write that exactly, but it’s right.
What are the best blocks to build a house with?
Cobblestone is a strong block and is easy to acquire, making it great for building houses.
Is it better to build a house with bricks or blocks?
HIGH THERMAL MASS – Because clay bricks have a high thermal mass, the brick walls absorb heat during the day and release it slowly at night, ensuring that the building maintains an even temperature. Houses built with clay bricks are usually warmer in winter and cooler in summer as opposed to houses built with cement blocks.
Why are concrete blocks good?
Lignacite is the original concrete block that founded the company of the same name in 1947. Based at the time, on a revolutionary mix of cement, sand and recycled wood shavings, it’s unique characteristics, meant it was an instant hit within the construction industry.
Through continued development, it has maintained its position as the block of choice for over 73 years. In more recent times, Lignacite has been used as the core building blocks ofsome of London’s most iconic buildings such as The Gherkin, The Shard and currently 22 Bishopgate and the Google Building.
The block is unlikely to be seen as it is the at the bottom of these high rise buildings, supporting the construction, providing the strength and stability to allow designers and developers to push boundaries of what can be achieved.It is regularly specified for commercial office buildings, schools, and apartments. Lignacite is available in Fair Faced, Paint Grade and Standard finishes. It is an ideal block for use in a wide range of commercial applications.
