# Cement Concrete Calculator

### 1. Cement Concrete Calculator

Given,

Length= 1 m

Depth= 1 m

Dry Volume = 1 m3

Wet mix volume = 1 x 1.54 m3

( Wet concrete is 54%-57% more because there is loss during preparation and also concrete contracts after drying)

For M20 Concrete

Cement : sand : aggregate = 1 : 1.5 : 3

Sum of all ratios = 1+1.5+3 = 5.5

Cement

Quantity of cement = (cement ratio / Sum of ratios ) * Dry volume
= (1 / 5.5 ) * 1.54
= 0.28 m3

The density of cement = 1440 kg/cub.m

Mass of cement = Volume of cement * Density
= 0.28 * 1440
= 403.2 kg

We know that each bag of cement is 50 kg

Number of cement bags = 403.5/50 = 8 bags

Sand

Quantity of Sand = (Sand ratio / Sum of ratios ) * Dry volume
= (1.5 / 5.5 ) * 1.54
= 0.42 cub.m

Density of Sand = 1450kg/cub.m

Mass of sand = 0.42 * 1450 = 609 kg

Aggregate

Quantity of aggregate = (aggregate ratio / Sum of ratios ) * Dry volume
= ( 3 / 5.5 ) * 1.54
= 0.84 m3

The density of Aggregate: 1500 kg/ cub. m

Mass of Aggregate: 0.84 *1500 = 1260 kg

Assuming Water cement ratio = 0.5

then, Quantity of water = 0.5 * Cement bag* 50 kg He is a founder and lead author of Dream Civil International and his civil engineering research articles has been taken as source by world's top news and educational sites like USA Today, Time, The richest, Wikipedia, etc.
