What is Concrete Mix Ratio?
In a normal mix concrete, the proportions of concrete are prefixed. Typically, nominal mix is used for small-scale constructions. For instance, in the case of M15 grade concrete, the ratio of cement to sand to aggregate is 1:2:4 which is a fixed ratio. Concrete grades from M5 to M20 come under the category of nominal mix concrete.

Compressive strength of concrete
The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete specimen and the maximum …
