Methods of Proportioning Cement, Sand and Aggregates in Concrete
Arbitrary Method of Proportioning Concrete. The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume. 1 : 1 : 2 and 1 : 1.2 : 2.4 for very high strength. 1 : 1.5 : 3 and 1 : 2 : 4 for normal works. 1 : 3 : 6 and 1 : 4 : 8 for foundations and mass concrete works.

Calculation of volume of aggregate in 1m^3 of concrete. Volume of aggregate = Ratio of aggregate / (Cement+Sand+Aggregate) x 1.57. = 3 / 5.5 x 1.57. = 0.86 m ^3. Now, assuming 1 cubic meter of aggregate = 1500 kgs (because the bulk density of every type of aggregate is different) Hence, 0.86m^3 of aggregate = 1500 x 0.86 = 1290 kgs.
