Question

Concrete is made by mixing cement, sand and gravel in the ratio 1 : 3 : 4.LILLY wants to make 2400kg of concrete. Calculate the amount of cement, sand and gravel which is needed to make the concrete.

Answer 1

Answer:

Weight of cement required can be calculated from multiplying the volume of cement with the bulk density of cement. The bulk density of frequently used cement varieties (both PPC and OPC) is 1440 kg/cu. m. Hence 8 bags of cement required to prepare one cubic meter of M20 grade concrete.
