Compressive Strength of Concrete Concrete Cubes. The capacity of concrete is reported in psi - pounds per sq inch in US units and in MPa - mega pascals in SI unitsThis is usually called as the characteristic compressive strength of concrete fc fck For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.
2020-7-7Till the late 1970s, the use of concrete in excess of M40 in tall buildings was not known. Now, with the effective use of admixtures and other sophisticated applications of concrete technology, it is easy to achieve a strength of 50 MPa in 12 to 18 hours, and above 70 MPa at 28-days.. It is feasible to produce concrete having a compressive strength of up to 150 MPa at 91-days.
