# C25 Concrete Mix Ratio

how to calculate quantities of cement, sand and aggregate,the dry volume of concrete mixture is always greater than the wet volume. the ratio of dry volume to the wet volume of concrete is 1.54. so 1.54 cum of dry materials (cement, sand and aggregate) is required to produce 1 cum of concrete. volume of cement required = 1/ (1+2+4) x 1.54 = 1/7 x 1.54 = 0.22 cum..types of concrete grade and their ratio as per british,nominal mix ratio of c25 concrete grade is 1 : 1 : 2, in which one part is portland cement mixed with 1 part of fine aggregate/sand and 2 part of coarse aggregate with required quantity of water to reach compressive strength 25 newton per square millimetre (n/mm2) or 25mpa at 28 days after mixing..
