| Abstrakt: | Formulas are presented for the relationship between composition and strength of concrete containing fly ash. Their extent of reliability is demonstrated by comparing the calculated values to empirical results taken from the literature. An optimization procedure based on differential calculus is also presented for the calculation of the most economical (optimum) fly ash content. Use of the formulas for proportioning fly ash concrete is illustrated. Though they do not eliminate the necessity of trial mixes in proportioning, these formulas should reduce the needed number of trials. It is also believed that the promising results of their paper call for further experimental and analytical work in the directions indicated on the effects of fly ash addition on the properties of concrete.
