The answer is simple. The density of cement is 1440 kg/cu.m, which means for 1 cu.m it occupies 1440 kg of cement. One bag of cement weighs 50 kg. Hence: 1440 Kg of cement occupies——————-> 1 cu.m 50 kg of cement occupies———————-> ? cu.m hence for ...Read More
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 cumRead More
For M20, the ratio of ingredients is:1(cement):1.5(fine aggregate or sand):3(coarse aggregate). Design Mix.
