Cement is an adhesive material of all kinds, a binding material used in building and civil engineering construction. Cement is a fine grinding powder that, when mixed with water,which then sets to a hard mass.Concrete is the most widely used building material in the world today, and cement production is widespread.

About 1-2 tonnes of concrete is poured each year in developed countries,depending upon the work and demand of construction works

we know that one bag of cement=50 kg,

1.volume of cement bags in meter cubes (1m³)
:

Number of cement bags required in 1 m³ = weight of cement in 1 m³/ weight of cement in 1 bag

so,the number of cement bags required in1 m³ = 1440/50 = 28.80 no.'s

volume of a one cement bag = 1 / 28.8 = 0.034722 m³

2. volume of a cement bag in cubic feet (cft) :

As we know, 1 m³ = 35.3147 cubic feet = 28.80 no. of bags

volume of one cement bag = 35.3147 / 28.80 = 1.226 cft (cubic feet)

3. volume of the cement bag in the litres
:

Volume of a cement bag = 0.0347 m³

since, 1 m³ = 10³ litres

= 0.034722 x 10³ = 34.4722 litres

volume of one cement bag = 34.4722 litres

1. Dry Density of Cement = 1440kg/m3

Each bag of cement consists of = 50kg

No. of bags in one cubic metre = 1440/50

= 29bags (approx)

10. Water /centre =0.5 this rait
