How to Calculate Cement Sand and Coarse Aggregate

How to Calculate Cement Sand and Coarse Aggregate

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

1:3:6 is M10 (1 cement:3 sand:6 metal) 1:2:4 is M15. 1:1 / :3 is M20. For calculating the cement content, by weight, required per m of concrete, use the formula 1440*K/A, where A is the figure of coarse aggregates (metal) in the ratio. K is a constant depending on the coarse aggregate (metal) size used.
