How to Calculate Quantities of Cement, Sand and Aggregate

Considering concrete density = 2400 kg/cum, One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft
