How to calculate Quantity of Cement, Sand, Aggregate & Water in M10 concrete?

In order to calculate the required quantity of Cement, Sand, Coarse Aggregates and water for M10 grade of concrete we have to follow 6 simple steps.

1. Assumptions

Volume of concrete = 1 m³

Grade of concrete M10  (1:3:6)

2. Find-out the Quantity of concrete (Wet volume & Dry volume)

Wet volume of concrete = 1 m³

Here, wet volume is nothing but Volume of the concrete after mixing with water.

∵ Dry volume = Wet volume x 1.54 (You can also take it as 1.50 to 1.55, But it became standard practice to considering 1.54 as multiplication factor).

what is 1.54 in concrete?

Dry volume of concrete = 1 x 1.54 =1.54 m³

3. Find-out quantity of Cement

∵ Quantity of cement = (Dry volume of concrete x cement ratio)/(sum of the ratio)

Cement = (1.54 x 1)/(1+3+6)=0.154 m³

∵ Density of Cement = 1440 kg/m³

Weight of Cement = 1440 x 0.154 = 221.76 Kg

∵ 1 bag of cement contains 50 kg of cement

Number of bags = 221.76 Kg/50 kg = 4.435 ≅ 5 No’s

4. Find-out quantity of Sand

∵ Cement : Sand :: 1:3

Quantity of sand =Quantity of cement x 3

∴ Quantity of Sand = 0.154 x 3 = 0.462 

∵ 1m³=35.3147 Cubic Feet (CFT)

Quantity of sand = 0.462 x 35.3147 = 16.315 CFT

∵ Weight of sand = volume x density, Density of Sand = 1600 kg/m^3 

∴ Weight of sand= 0.462 x 1600=  739.2 kg (0.739 tonnes)

5. Find-out quantity of Coarse Aggregates

∵ Cement : Coarse Aggregates :: 1:6

Quantity of sand =Quantity of cement x 6

∴ Quantity of Coarse Aggregates = 0.154 x 6 = 0.924 

∵ 1m³=35.3147 Cubic Feet (CFT)

Quantity of Coarse Aggregates = 0.924 x 35.3147 = 32.630 CFT

∵ Weight of Coarse Aggregates = volume x density, Density of Coarse Aggregates = 1520 kg/m^3 

∴ Weight of Coarse Aggregates = 0.924 x 1520 =  1404.48 kg (1.404 tonnes)

6.Find-out quantity of water

Assume water cement ratio as 0.50

Quantity of water =  221.76 x 0.50 = 443.52 Liters
