Question { Paras, 142524 }

how many cement use for 1cum concrete for 25Grade.

Answer

Dry Volume for 1 Cum Mix is 1.54 Cum.

Ratio for M25 is 1:1:2 = 1+1+2 = 4

1 Part of cement would be = 1.54/4 = 0.385 cum.

1 bag of cement = .035 cum

total bag of cement = 0.385/.035 = 11 bags

1 bag of cement = 50 kg of cement

11 bags = 50 x 11 = 550 kg of cement

cement required for 1 cum of m25 grade concrete is 550 kg.
