✦ Synopsis

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 age strength and there have been many efforts to predict and/or to improve this m recent years, so that these concretes can be utilized appropriately. Thus a quantitative understanding of the early age strength behaviour of fly_.ash concretes frill help in designing the concrete for any specific requirement. Tlais investigation, assumeO on the most recent results available, predicts the same through the efficiency concepts at the different percentages of fly ash replacement.

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
