#### What is difference between concrete and cement?

What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement.

### How many bags of cement do I need for a 1000 square foot house?

How many cement bags in 1000 sq ft? – 1000 square feet house cement calculator method has already been explained in the previous responses. So, I am just going to add a few points which I feel are really important for us to know. Making mortar from cement, aggregate, gravel, and water is crucial in the construction industry.

- In masonry construction, the mortar serves as glue and bedding that ties together and fills the spaces between bricks, stones, or concrete.
- Concrete, tiling, plaster, and brickwork all employ it.
- A helpful hint for choosing the correct cement is that it must feel soft and sink instead of float when a small amount of it is placed in water.

For the most part, mixed cement (P.P.C. & P.S.C.) is chosen for masonry, tiling, and plastering, whilst O.P.C.53 grade is frequently employed for the production of concrete.0.40 kilogramme of cement is needed for every square foot. Therefore, the amount of cement required for a 1000 sq ft area is calculated by multiplying the built-up area by 0.40 kg.400 bags of cement make up the whole quantity of construction materials.

#### How many bricks does it take to cover 100 square feet?

Guide on how many bricks required for 100 square feet: – 1) As per Indian standards, the basic and normal brick dimension is 8′′4′′4′′ (length width height).2) Start by multiplying the length and height. For example, 8 inches long by 4 inches broad = 32 square inches.1 sq foot Equals 12′′ X 12′′ = 144 sq inches 3) To calculate the exact quantity of bricks per square foot, divide 32 sq inches of one brick by 144, for example, 144/32 = about 4.5 nos, thus you’ll require 4.5 nos of bricks per square foot.

Bricks required in a single layer 4.5″ brick wall of 100 square feet: In order to determine the specific number of bricks in 100 square feet, multiply the structure’s square footage by 4.5.100 X 4.5 = 450 bricks, so 450 bricks are required per 100 square feet for a 4.5-inch brick wall with a single layer.

Bricks required in a single layer 9″ brick wall of 100 square feet: Calculate the specific amount of bricks in 100 square feet by multiplying its square footage by nine. As an example, 100 X 9 = 900 bricks, thus a complete (double layer, 9′′) brick wall will require 900 bricks.

Bricks required in a single layer 13.5″ brick wall of 100 square feet: The bricks in a 100 square foot wall will need to be multiplied by 13.5 in order to determine the required number of bricks, such as 100 * 13.5 = 1350 bricks, so a full (triple-layer, 13.5′′) brick wall will require 1350 bricks. This guides you about how many bricks in 100 square feet are required.

#### How much does it cost to build a 10×10 room?

One room construction cost (10’×10′) | Latest estimation in 2021 –

- Construction of one room and their cost calculation require quantity of material and their cost labour cost and cost of finishing like PCC flooring plastering tiling electrical fitting plumbing and water sanitization. Cost of construction of one room size 10’×10′ consist of material required and their estimation of following:-
- ● Foundation PCC plinth beam and their cost.
- ● brick cost calculation, number of bricks, quantity of cement sand and their cost.
- ● concrete work, column, beam and slab.
- ● reinforcement quantity and their cost
- ● tile flooring quantity and their cost
- ● labour work and their cost.
- 1) Footing/ Foundation cost for room size 10’×10′.

Let Foundation size is 4’×4′ and 4 feet depth, so volume of soil excavation for 4 footing = 4× 4’×4’×4′ = 256 cubic feet. Converting into cubic meter 256/35.32 =7.25m3. Soil excavation rate is around rs 800 per m3 for hard soil and rs 300 per m3 for soft soil.

- We take soil excavation rate Rs 400/m3 for this calculation.
- Total cost of soil excavation for foundation = 7.25 × 400 = Rs 2900.2) brick work quantity and cost calculation Assume room 10’×10′ have 9″ brick wall on four side height up to 10 feet and parapet wall for partition wall will be of 4.5 inch.

Outer dimension of room is 11.5’×11.5′ and inner dimension of room excluding brick wall is 10’×10′.

- Area of one brick wall =10’×10′ =100 sq foot Area of 4 brick wall =4 ×100 = 400 sq foot.
- Door size = 4’×7′ = 28 sq ft
- Window size = 3’×4’= 12 sq ft
- Door and window size should be deducted from total area of brick wall.
- Net area of brick wall= 400 _ (28+12)= 360 sq ft

Volume of 9 inch thick brick wall = 360×9/12 = 270 cubic feet, converting into cubic meter we have 270/35.32=7.65 cubic meter. Consider parapet brick wall 3.5 feet height 4.5 inch thick, and outer dimension of room is 11.5’×11.5′ = 132.25 sq ft, total area of parapet brick wall on all four side = 11.5 × 3.5 ×4 =161 sq ft.

- Volume of parapet wall =( 4.5/12)×161=60 cubic ft, converting into cubic meter,60/35.32 = 1.70 cubic meter.
- Total brickwork = 4 brick wall + parapet wall = 7.65+ 1.70 = 9.35 cubic meter.
- Thumb Rule for brickwork 1 cubic metre of brickwork require 500 bricks, 1.26 bags of cement and 9.28 cubic feet sand quantity.

● Brick quantity and their cost : number of brick in 9.35 cubic meter = 500×9.35= 4675 nos, suppose first class brick rate is around rs 8000 per thousand, so brick cost = 8000× (4675/1000) = rs 37400. ● cement quantity and their cost :- quantity of cement required for 9.35 cubic metre brickwork is 1.26 × 9.35 = around 12 bags cement.

- Suppose market rate of cement is around rupees 400 per bag so cement cost = 12×400= rs 4800.
- Sand quantity and their cost :- quantity of sand required for 9.35 cubic metre brick work is 9.28 × 9.35 = 87 cft.
- Market rate of sand is around rupees 40 per CFT then sand cost= 87 ×40 = rs 3480.
- So total brickwork cost = brick cost + cement cost + sand cost = 37400 + 4800 + 3480 = rs 45680.3) concrete quantity and cost calculation for footing,column,plinth beam,wall Beam and rcc slab.

Footing is 4 feet depth and column size is 9 inch into 12 inch and height of column is 10 feet up to slab and 3.5 feet above slab. There is four column. So column length is = 4’+10’+3.5’= 17.5′ Total volume of concrete quantity for 4 column = 4 × (9″×12″)×17.5′ = 4 × 13.125 =52.5cubic feet.

- Plinth beam size 9″×12″ for all around for length 11.5×4 = 46 feet.
- Total volume of concrete quantity for plinth beam = (9″×12″)× 46 = 34.5 cubic feet.
- Wall beam size 9″×9″ for all around for length 11.5×4 = 46 feet.
- Total volume of concrete quantity for wall beam = (9″×9″)× 46′ = 25.9 cubic feet.
- RCC slab 5 inch thick for 11.5’×11.5′, concrete volume is 11.5’×11.5’×5/12′ = 55 cft.

Total Weight volume of rcc concrete = concrete quantity for column + concrete quantity for RCC plinth beam + concrete quantity for RCC wall + concrete quantity for RCC slab = 52.5 +34.5+25.9+55 = 170 cft. Converting 170cft into cubic metre,170/35.32 = 4.8m3.

Ready mix concrete available in market is around rupees 4000 per m3 for M20 grade of concrete, so total material cost of concrete = 4000×4.8 = rs 19200.4) reinforcement cost and quantity calculation :- suppose reinforcement required is 1% of concrete volume for RCC work like footing column beam and RCC slab.

Steel quantity = (1/100)×4.8m3 = 0.048m3 Weight of steel = 0.048m3 × 7850kg/m3 = 376.8kg, market rate of Steel is around 60 rupees per kg then total cost of Steel = 60×376.8 = rs 22600.5) labour cost for construction of house around 180 rupees per square foot without plastering and PCC or tile flooring.

- Total construction cost for one room = 2900+45680+19200+22600+23805 = Approx rs 114200.
- Construction cost for one room 10’×10′ with parapet wall is around rs 114200, this total cost includes soil excavation cost rs 2900, brickwork cost rs 45680, concrete cost rs 19200, steel cost rs 22600 and labour cost rs 23805 without plastering PCC and tile flooring.
- Consider finishing cost is about 60% of total construction cost of one room, finishing should be required plastering, PCC flooring, tile flooring, putty painting, electrical fitting, plumbering, water and sanitization.
- 60% of construction cost of one room = (70/100)×114200= 68520.
- Total cost =114200+68520 = rs 182700.
- Total construction cost for fully furnished one room 10’×10′ is around rs 182700, this total cost includes cost of building construction, plastering, PCC flooring, tile flooring, electrical fitting, plumbing, painting putty and water and sanitization.
- 10*10 room construction cost in India:- in india, total construction cost for fully furnished one room 10*10 is around Rs 182700, this total cost includes cost of building construction, plastering, PCC flooring, tile flooring, electrical fitting, plumbing, painting putty and water and sanitization.

## Is it hard to lay your own concrete?

You can build a DIY concrete patio step by step It’s easy to pour and build a backyard patio made of concrete in this How To article. On a small scale, concrete is fairly easy to work with, but installing an entire patio can be a challenge. It is possible to build an attractive concrete patio yourself, but careful planning and preparation is necessary.

Be sure to place all the concrete at once; a big patio can be broken down into smaller manageable sections using 2×4’s. Once concrete is in place, you’re stuck with it forever; replacement is costly and difficult. Planning is essential for a perfect DIY conrete patio. Build and install forms, making sure they’re level and properly graded for drainage.

To prevent rain puddles from forming, design a 2% slope (every 10′ long will drop 2.5″). Place and level a 4″-6″ bed of gravel; you need a gravel base in areas of poor drainage or freezing temperatures. Be sure to compact the gravel base and rent a compacting machine if necessary.

- Check gravel thickness with a homemade template that extends down from the tops of the forms 4″ of the finished patio; when it just touches the top of the gravel, the base is thick enough.
- A taller slab will be stronger- we recommend 4″ thick.
- Let the gravel extend under the edges of the forms.
- If the patio will abut an existing concrete patio or slab, install isolation-joint strips.

Attach the strips flush with the top of an existing slab using hardened concrete nails or construction adhesive.

## How many 12×12 tiles do I need for 100 square feet?

When I did my very first tile project I remember calculating how many 12×12 tiles for 100 square feet. Adding new tile is a great way to improve the overall look and feel of a space. When you are planning your project and purchasing supplies it is important to be able to estimate approximately how many tiles you will need based on the size of the space.

- For a 100 square foot tile project, you will need to install a total of 100 12×12 tiles.
- But some tiles could be damaged during transport or installation or maybe otherwise unusable.
- It’s customary to purchase an additional 15 percent above the exact calculated amount of tile.100 (12×12 tiles) times 15% equals 115 tiles.

The extra tiles will help ensure that you have enough tiles on hand to finish the project even if some of the tiles you purchased cannot be installed for any reason.
