The volume method, which uses bags of cement and a measuring box as a reference for sand and gravel, has long been practiced by almost all types of concrete construction. However, in larger and bigger scale projects and in sites where mixing and material storage is not possible, ready-mixed concrete is used.

More2022-1-11 The volume proportion in weight turns out to be. Cement : Sand : Aggregate (in Kgs) is 50 kgs : 115 kgs : 209 kgs (by weight) Water required for the mixture = 27.5 kgs. Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum
