If you are planning on constructing a house, you must have a lot of queries obviously. How much cement required for 1 sq feet area or how should I do the interiors and many others. It’s good that you are doing your own research and trying to gauge everything around constructing a house.

Trust me it’s not an easy job and being informed is the right way to start things up. So I am going to help you with this. How much cement required for 1 sq feet area Construction agents and builders can sometimes misguide on this if their only motive is to earn through the contract rather than helping you to fulfil your dreams so make sure that first, you get the good lot.

Now when it comes to deciding the numbers you will have to understand that a lot goes behind it. You have to think about what type of construction you are going for, how the soil, structuring and much more. Here is an example for you to determine the cement requirements as requested by you: Assuming that we opt for M20 grade of concrete in which cement sand and aggregate ratio is 1:1.5:3 and cement weight is 15043.4 kg and 1 cement bag weighs 50 kg for a construction of a 1000 sq ft home.

#### How many bags of cement do I need for 100 square feet?

How many bags of cement for 100 sq ft 20mm external wall plastering – Given area = 100 sq ft Thickness = 20 mm Cement mortar ratio = 1:5 ( 1 part cement and 5 part cement) Total ratio = 1+5 =6 Part of cement = 1/6 10.76 sq ft = 1 square meter 100 sq ft = 9.294 sq m Volume of plastering = 9.294 × 0.02 = 0.186 m3 = 0.186 cubic meter Wet volume = 0.186 m3 Dry volume = 0.186 × 1.33 = 0.247 m3 Cement weight = 1/6 × 0.247 × 1440 = 59 kg 1 bag cement weight = 50 kg Bags of cement = 59/50 = 1.187 1.187 bags (59 kg) of cement is required for 100 sq ft 20 mm thick external wall plastering.

#### How many bags of cement do I need for 1 square meter?

Step 5: Volume of Cement in Kg. – Calculating the cement consumption for the plastering work in kg. Volume of Cement in Kg. = x Volume of Cement Volume of Cement in Kg. = 1440 x 0.0028 Volume of Cement in Kg. = Density of Cement x Volume of Cement Volume of Cement in Kg. = 4.032 Kg We know that,

- The density of cement is 1440 kg per m 3
- There are 0.08 cement bag is required for the plastering work of one square metre,

### What is the ratio of 1 bag of cement?

Cement, Sand and aggregate requirement for Different grade concrete –

Grade of Concrete | Nominal Mix Proportion | Cement Required (bag)/cum | Sand Required (in cft) | Aggregate Required (in cft) |
---|---|---|---|---|

M15 | 1:3:6 | 4.5 | 16.04 | 32.07 |

M20 | 1:2:4 | 6 | 14.98 | 29.96 |

M25 | 1:1.75:3.5 | 6.75 | 14.75 | 29.14 |

M30 | 1:1.5:3 | 7.5 | 14.06 | 28.11 |

Incase you want to convert the requirement of Sand and Aggregate in Cum; 1 Cum = 35.31 Cft Eyeopener :Many popular blogs claim M20 nominal mix as 1:1.5:3,however we strongly differ by same.Through this blog,we are also trying to address the same myth which is being carried forward since last 4 decades.

The reason being: With constant research and development in the field of cement technology and its manufacturing process,a M20 mix of “1:1.5:3″(by volume) would be too rich, over engineered and uneconomical (~7.5 bags of cement per cum) and will ultimately result into a M30 concrete and above (IS:456 too have the minimum cement/cementitious content of 06 bags for M20).

As the latest generation of 53 grade OPC cement is ultimately giving a strength of 65 to 70 MPa at 28days, 1:2:4 will give a strength of M20. A detail procedure to calculate the cement bags required for 1: 2 :4 mix (~6 bags of cement per cum) is shown below.

#### How much cement is need for 10×10?

What equation should I use to find out how much concrete I need? – How to calculate concrete:

- 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

Here’s what the math looks like for a 10′ by 10′ concrete patio:

- 10 x 10 = 100 square feet
- 4 ÷ 12 =,33
- 100 x,33 = 33 cubic feet
- 33 x,037 = 1.22 cubic yards

Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size:

- 40 pound bag yields,011 cubic yards
- 60 pound bag yields,017 cubic yards
- 80 pound bag yields,022 cubic yards

### How much does 25kg of cement cover?

As a rule of thumb 1 of our 25kg bags will cover an area of 0.25m to a recommended depth of 50mm.

### What area does a bag of cement cover?

One 20kg bag will cover an area of 1.1m2 to a depth of approximately 10mm. or 108 x 20kg bags equates to one cubic metre of mixed concrete.

Grade M20 concrete ratio – M20 grade concrete has a notional cement-to-sand-to-aggregate-to-water ratio of roughly 1:1.5:3, with the water-cement ratio being kept between 0.4 and 0.6. It is composed of a mixture of cement, sand (fine aggregates), and coarse aggregate. Source: Pinterest

## How many bags of concrete do I need for a 10×10 square?

How many bags of concrete do I need for a 10×10 slab at 4 inch thick – At 4 inch thick, for a 10×10 slab, you will need either seventy four 60- pounds or fifty six 80- pounds or 112- 40- pounds bags of concrete. Thus, either 74- 60lb or 56- 80lb or 112- 40lb bags of concrete will be required for a 10×10 slab at 4″ thick.

- Mathematical calculation:-
- 1) Yields of 40lb bag = 0.011 cubic yards,
- 2) Yields of 60lb bag = 0.017 cubic yards
- 3) Yields of 80lb bag = 0.022 cubic yards
- 4) Yields of 90lb bag = 0.025 cubic yards
- 5) Total required concrete quantity for 10×10 slab at 4 inch thick = 1.23 cubic yard

6) No. of bags of 40lb of concrete = 1.23/ 0.011= 112 bags, 7) No. of bags of 60lb of concrete = 1.23/ 0.017= 74 bags, 8) No. of bags of 80lb of concrete = 1.23/ 0.022= 56 bags, 9) No. of bags of 90lb of concrete = 1.23/ 0.025 = 49 bags,
