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
Determine how much coarse aggregate and fine aggregate you need for your mixture. Making concrete is a delicate balance, particularly if you are going to make ultra high performance concrete. The standard ratio is 11 percent Portland cement, 41 percent coarse aggregates (such as gravel or crushed stone) and 26 percent fine aggregates, such as sand.
