5) Impact strength: the maximum impact or suddenly applied force a part can take before its failure. It's actually used to measure the amount of energy the material can absorb at the limited state. 6) Shear strength: the maximum shear load a material can withstand before failing divided by its cross-sectional area.

I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give high-density concrete. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate …
