Abstract:Studies relating to proportioning of concrete incorporating pulverized-fuel ash (pfa) as a partial replacement of cement (OPC/PFA concrete) are reviewed. Three different approaches are identified: simple replacement, modified replacement and rational methods and their implications are discussed, particularly effects on the properties of resulting concrete, practical appli-cations and the optimum utilization of fly ash. It is suggested that OPC/PFA concrete should be designed without reference to control OPC concrete and a mix design method is proposed for this purpose which is sufficiently simple for use in practice and is similar to current practice for OPC concrete design. It is hoped that this may lead to the development of a more widely acceptable mix design method for OPC/PFA concrete.
