✦ Synopsis

Five fly ash concretes were found to gain considerable strength beyond 28 days when standard cured in water at 20°C. However, strength development came to an almost complete stop after 3½ years, at what time the fly ash activity factors with respect to concrete compressive strength ranged from 0.86 to 0.93.

A factorial experiment was designed to measure the sorptivity of cement and fly ash concretes in order to compare the durability of fly ash concrete against the -cement concrete. Sorptivity measurements based on the capillary movement of water was made on three grades of cement concrete and six grad

The effectiveness, K, of a fly ash can be defined as the ratio of the amount of cement replaced to the amount of fly ash added, provided the specified requirements of the concrete are maintained. It is generally assumed that the effectiveness of a fly ash can be treated as a constant. This paper pre
