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

To shape concrete, aggregate is mixed with cement that is used to lay the base of a road or even a roof in a building. Many ingredients, such as sand, gravel, stone, crushed rock and sometimes even waste slug from the iron and steel industry, are used to form aggregates. In general, aggregate is graded as fine and coarse.

Proper calculation and relative proportioning of materials are important to produce a good quality concrete. Let’s see some simple techniques used by engineers to calculate cement, sand, coarse aggregate (gravel or Jalli) and water needed to produce different grades of concrete, like M5, M7.5, M10, M15 and M20.
