Five fly ash concretes were found to gain considerable strength beyond 28 days when standard cured in water at 20ยฐC. However, strength development came to an almost complete stop after 3ยฝ years, at what time the fly ash activity factors with respect to concrete compressive strength ranged from 0.86

The effects of two super water-reducing admixtures on the compressive strengths and elastic moduli of portland cement mortars containing fly ash were determined. The results show that the effectiveness of the chemicals for improving the strengths of mixtures in which portland cement is partially re

The strength of concrete at early ages has assumed a co~iderable significance in recent years due to the several specific requirements ot the modern construction industry, like the early striking or forms, early transfer of prestress etc. However, fly ash concretes are known to-have a lower early ag

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
