...### Calculate Sand & Gravel per 50kg Cement Bag in Volume

Apr 30, 2020· Hence for every 1 part of cement, we have to use 2 part of sand and 4 part of gravel to get M15 ratio concrete. The volume of 50 kg cement bag is 1.25 CFT. We can check this value by dividing the weight of the cement bag by the bulk density of cement. The volume of batching box used in the construction site is also 1.25 CFT.
