Home / What Is Cement Concrete Ration In M25 Grade
Assume we need 1 m3 of wet volume concrete of m25 mix mix ratio m25 1 1 2 so total parts 112 4 parts which gives dry volume that means before adding water content volume of concrete 1 cement part4 1 sand part4 2 coarse aggregate part4 therefore volume of cement 14 x 155 volume of sand 14 x 155.
