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.

$\sigma ={\frac {A}{B^{w/c}}}$

where:

A, B are constants
w/c is the mass ratio of water to cement
