Workability of concrete incorporating pulverized fuel ash and metakaolin

摘要

Workability of concrete incorporating combinations of pulverized fuel ash (PFA) and metakaolin (MK) as partial replacements for Portland cement (PC) has been investigated, The aim of the research work is to explore the potential of using PFA and MK as blends with PC in terms of the flow properties of the resulting concrete. Ninety mixtures containing 1, 10, 20, 30 and 40/100 total replacement of cement with combinations of metakaolin (0-15/100) and PFA (0-40/100) for concretes with water to binder ratios of 0.4, 0.5 and 0.6 were prepared.
