# Cement Concrete Calculator

### 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 = 1440 kg/m3Density of = 1450-1500 Kg/m3Density of Aggregate = 1450-1550 Kg/m3Weight of Cement in 1 Bag = 50 KgVolume 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 = (Own Ratio/ Total sum of ratio) * Dry Volume

= ( 1.5/5.5 ) * 1.54

=  0.42 m³

#### iii. Aggregate Quantity Calculation

Quantity of = (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
