What is the mix ratio for C20, C25, C30, C35 and C40 concrete
The common concrete mix ratio to create C20 grade of concrete is 1 : 1.81 : 3.68 : 0.51 (cement: Sand: Stone: water) by weight. This means, 1m3 of C20 grade of concrete can be prepared by mixing of 1 part of cement (343kg of cement) + 1.81 parts of Sand (621kg of Sand) + 3.68 parts of Stone (1261 kg gravel) + 0.51 parts of water (175kg of water).احصل على السعر
