1. Cement Concrete Calculator Example
One example of materials calculation of cement concrete is given below:
Data per 1 m³ of M20 Concrete Ratio
| Material | Volume Required (m3) | Materials Required in kg |
| Cement | 0.28 | 403.2 |
| Fine Aggregate | 0.42 | 619.85 |
| Coarse Aggregate | 0.84 | 1359.82 |
| Water | 0.190 | 190 kg ( Average ) |
| Things To Know!! Density of Cement = 1440 kg/m3 Density of Sand = 1450-1500 Kg/m3 Density of Aggregate = 1450-1550 Kg/m3 Weight of Cement in 1 Bag = 50 Kg Volume of 1 Bag of Cement in Cubic meter = 0.03472 m3 |
Now, Taking
Grade of Concrete = M20 Concrete
Mix Ratio = 1:1.5:3
Total sum of ratio =1+1.5+3 =5.5
Wet volume of Concrete = 1 m3.
To get dry volume, wet volume increased by 54%
Dry volume of concrete = 1 + 0.54 = 1.54 m³
i. Cement Quantity Calculation
Quantity of cement = (Own Ratio/ Total sum of ratio) * Dry Volume
= ( 1/5.5 ) * 1.54
= 0.28 m³
Cement in kg = volume of cement * density of cement
= 0.28 * 1440
= 403.2 kg
ii. Sand Quantity Calculation
Quantity of sand = (Own Ratio/ Total sum of ratio) * Dry Volume
= ( 1.5/5.5 ) * 1.54
= 0.42 m³
iii. Aggregate Quantity Calculation
Quantity of aggregate = (Own Ratio/ Total sum of ratio) * Dry Volume
= ( 3/5.5 ) * 1.54
= 0.84 m³
iv. Water Calculation
For inferior-quality concrete: W/C ratio = 0.5
For superior-quality concrete: W/C ratio = 0.45
Minimum amount of water required per m³ = 0.45 * 403.2 = 181.44 kg
Maximum amount of water required per m³ = 0.5 * 403.2 = 201.6 kg
