The strength of concrete at early ages has assumed a considerable significance in recent years due to the several specific requirements of the modern construction industry, like the early striking of 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 in recent years, so that these concretes can be utilized appropriately. Thus a quantitative understanding of the early age strength behavior of fly ash concretes will help in designing the concrete for any specific requirement. This investigation, assumed on the most recent results available, predicts the same through the efficiency concepts at the different percentages of fly ash replacement.
