Abrams' law
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/Bw/c
S = strength of concrete
A and B are constants
w/c is water-cement ratio varies from 0.3 to 1.20
