how to calculate cement in m 30 mix concrete

2020-11-13  If we Assume the required cement volume as 50kg, Required amount of water = W/C Ratio X Cement Volume. Therefore, Required amount of water = 0.5 X 50 kg = 25 litres / 50 kg cement bag. Aim for a mix of 1 part cement, 2 1/4 part sand and 3 parts aggregate. Mix the dry cement and sand, add water, mix, then add aggregate, and more water as needed.
