What is the size of construction block? – Concrete blocks are light and common in various sizes a standard concert block is 600mm x 250mm x 150mm is equivalent to by about 8 red clay bricks, the weight of one single block is about 14kg where is 8 red clay bricks is 36kg that is more than double.
Which is the common size for using building blocks in construction? The common size of concrete blocks is 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. Cement, aggregate, water is used to prepare concrete blocks. The cement-aggregate ratio in concrete blocks is 1:6.

UNIT SIZES – Typically, concrete masonry units have nominal face dimensions of 8 in. (203 mm) by 16 in. (406 mm), available in nominal thicknesses of 4, 6, 8, 10, 12, 14, and 16 in. (102, 152, 203, 254, 305, 356, and 406 mm). Nominal dimensions refer to the module size for planning bond patterns and modular layout with respect to door and window openings.
- Specified 3 dimensions of concrete masonry units are typically 3/8 in.
- 9.5 mm) less than nominal dimensions, so that a 4 or 8 in.

In addition to these standard sizes, other unit heights, lengths, and thicknesses may be available from local concrete masonry producers. Standard Specification for Loadbearing Concrete Masonry Units, ASTM C90 (ref.1) is the most frequently referenced standard for concrete masonry units.
ASTM C90 includes minimum face shell and web thicknesses for the different sizes of concrete masonry units as listed in Table 1. Overall unit dimensions (width, height, and length) are permitted to vary by ± 3/8 in. (3.2 mm) from the specified dimensions. Where required, units may be manufactured to closer tolerances than those stipulated by ASTM C90.

ASTM C90 also defines the difference between hollow and solid concrete masonry units. The net cross-sectional area of a solid unit is at least 75% of the gross cross-sectional area. In addition to the unit sizes above, concrete brick complying with ASTM C1634, Standard Specification for Concrete Facing Brick (ref.2), are available in a wide array of nominal lengths and heights; typically with a nominal 4 in.

What is the weight of a concrete block? per cubic feet or more, a standard 8x8x16 Heavy Weight block weighs approximately 35 lbs. Medium Weight blocks are available on a special order basis. At 105-125 lbs. per cubic feet, a standard 8x8x16 Medium Weight block weighs approximately 32 lbs.
What is the average size of a concrete block?
What Is the Weight of One Standard Concrete Block? Sollina Images/Blend Images/Getty Images The weight of one standard concrete block ranges between 38 and 50 pounds. All standard concrete blocks have a uniform size; however, the weight of each block may differ owing to a number of factors. The size of a standard concrete block is 8 inches in depth, 8 inches in height and 16 inches in width.
- However, the weight of a standard concrete block varies owing to varying cement concentrations in the block.
- Also, the weight of the concrete block made at one plant differs from that made at another since the materials used are different.
- Even blocks made at a single plant may not weigh the same, although they tend to have a uniform weight since the same material is used to make them.

Factors For Cost – © n_defender/Shutterstock Wood fence with tools No matter what kind of wooden fence you are trying to build or what type of wood you are planning to use, there are going to be a variety of basic factors that influence the final purchase price of your new fence.
- Angi has a good breakdown of many of the basic details that homeowners should think about when embarking on their fence journey.
- Fence height and length It stands to reason that the taller you want your fence to be, and the larger the area you want to be fenced in, the more it is going to cost you -– because obviously, a longer and taller fence will, of course, require more wood.
Most fence contractors offer default heights of 4, 5, or 6 feet. If you want your fence to go over 6 feet, which offers the most privacy and protection, you will likely be charged anywhere between 20% and 30% more than for a standard fence height. If you want a taller fence, it may make more sense to go the DIY route to avoid that additional charge.
- But if you are looking at installing a particularly long fence, regardless of its height, you will likely want to find a contractor to install your fence for you.
- The longer your fence, the larger volume of wood you will need, and contractors are usually able to buy their materials in bulk, which lowers the overall cost.
Materials and tools Constructing a wooden fence requires a ton of materials besides the wood itself, not to mention the tools to work with those materials. The process of building a wooden fence involves drilling holes in the ground for the fence posts, mounting the posts, and then building out wooden slats in between the posts.
To drill the ground holes, you will need an auger. A power auger can cost you between $60 and $600, although you can rent one for a daily rate of between $50 and $100. A manual auger is significantly cheaper, usually anywhere between $15 and $110 to buy outright (though it should be noted that whatever a manual auger saves you in dollars, it costs you in blood, sweat, and tears).
Once you have drilled your holes, it’s time to fill them. Although you can choose to place your fence posts directly into the ground, the most stable and durable option is to set them in concrete instead. You can buy concrete in bags, usually around 80 lbs., costing $8 to $10 per bag.
- You will usually need anywhere between one and four bags for each post, depending on how tall and thick your posts are.
- Mounting the posts into the concrete and adding the slats for the fence itself will require screws, a drill, drill bits, an air compressor, and a finish nailer.
- You will need to make sure anything metal that goes into the final fence itself, such as your screws and nails, is made out of stainless steel.
According to HomeGuide, any other type of steel, including both galvanized and non-galvanized, will bleed black when it gets wet, leaving deep, unsightly stains on your pretty new wooden fence. Best avoided if at all possible. Labor Of course, you could decide not to spend any money on your own tools or materials and instead outsource the building of your wooden fence to a fencing company or independent contractor.
- While this approach will save you time and likely some cost on materials, your overall cost will probably be higher if you go the contractor route.
- Most companies will charge you by the linear foot, giving you the quote already mentioned for professional installation: between $10 and $30 per foot.
- Some fencing businesses, however, may charge you by the hour, usually between $25 and $60 per hour of work.
For a fence between 100 and 200 feet long, you can expect between one and three full days of work from your contractors, so they would charge you a total amount anywhere from $200 to $1440. Another advantage of working with a contractor is that they will usually give you some kind of warranty on your finished fence.
That way, if your fence falls apart, rots, is knocked over by a tree or is otherwise damaged, you can receive a free repair or replacement if the event occurs within the warranty period –- not an option if you choose to build your fence yourself. Location Depending on where you want your fence to go, you may have to deal with additional costs related to location.
If your fence is going to go up or across a hill, you will be charged more for the extra trouble to build –- and in some situations, the hill may be so steep that building a fence on it would be impossible or dangerous, in which case you will need to pay to have the ground leveled.
Leveling an area can set you back anywhere from $500 to $5000, according to HomeServe, so think carefully about where you want your fence to go and if it’s worth the extra funds. Other location costs may be less obvious. Digging holes for fence posts is an already laborious task, and it can be made even more complicated by the presence of rocks or clay in the soil.
Some contractors will charge more upfront for tricky soil conditions. If your contractor does not charge you upfront, you may still end up paying more for rough soil work if they are charging you by the hour, as it will take significantly longer for them to dig out rocky soil.
How do you calculate concrete block?
- Determine how thick you want the concrete
- Measure the length and width that you’d like to cover
- Multiply the length by the width to determine square footage
- Convert the thickness from inches to feet
- Multiply the thickness in feet by the square footage to determine cubic feet
- Convert cubic feet to cubic yards by multiplying by.037
