Abstract

The paper, which summarises a survey and an analysis of empirical strength laws, was undertaken with a view to formulating a strength law interrelating the water-cement ratio-which determines the porosity of the hardened cement-paste-and Powers's Gel/Space ratio, giving the relative strength of the cement stone.

Accordingly, a graphical procedure is given for predicting the strength of ordinary concretes for a given water-cement ratio and lean air-entrained concretes for a given “equivalent” water-cement ratio.

Compressive strength may also be predicted by means of numerical formulae.
