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 mass ratio 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/B^w/c

S = strength of concrete

A and B are constants

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