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 proportional 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 = strength of concrete

K = a constant

c, w & a = volume of cement, water & air respectively
