Question

A sample of concrete has a compressive strength of 21.07 MPa in dry state and in its

saturated state, its compressive strength is 14.25 MPa. Find the Softening Coefficient of the

material.

Answer 1

coefficient of softening (K)= ratio of compressive strength(Ko) of fully saturated material to that of same material when dry(Kg)

K= Kg/Ko

K= 21.07MPa/14.25MPa

K= 1.4786
