The mix proportion of a concrete is cement: river sand: Gravel = 1:2.02:3.71 (mass ratio) and the water cement ratio is 0.57

The mix proportion of a concrete is cement: river sand: Gravel = 1:2.02:3.71 (mass ratio) and the water cement ratio is 0.57

1+2.02+3.71+0.57=7.3Kg/m3
Cement = 1 / 7.3 * 2410 = 330.13kg/m3
Sand = 2.02/7.3 = 666.88kg/m3
Crushed stone = 3.71/7.3 = 1224.81kg/m3
Water = 0.57/7.3 = 188.18kg/m3
Total 2410
