BUILDER'S ENGINEER: Concrete Production - Volume Batching

Oct 26, 2015 · Volume Batching: concrete mixes are often quoted by ratio such as 1 : 2 : 4 (cement : fine aggregate or sand : coarse aggregate). Cement weighing 50 kg has a volume of 0.033 m3 therefore for the above mix 2 x 0.033 (0.066 m3) of sand and 4 x 0.033 (0.132 m3) of coarse aggregate is required.
