Question

Explain in detail the Abram’s Law.

Answer 1

Abrams' law (also called Abrams' water-cement ratio law)[1] is a concept in civil engineering. The law states the strength of a concrete mix is inversely related to the massratio of water to cement.[1][2] As the water content increases, the strength of concrete decreases.

Abrams’ law is a special case of a general rule formulated empirically by Feret:


S=A/Bw/c

S = strength of concrete

A and B are constants

w/c is water-cement ratio varies from 0.3 to 1.20
