Abstract : Extensive research has been carried out on investigation based on compressive strength development in concrete containing variable percentages of fly ash. The researches have proved that the pozzolanic reaction has always significantly contributed towards compressive strength gain in concrete. However, it is observed that many chemicals leach out from the concrete blocks during curing. Extensive analysis of curing water and the relevance of the chemical leaching out on the strength gain and formation of permeable voids is not seen in the literature. As the outcome of the ongoing research, this paper discusses the chemical analysis in relevance to pH and total alkalinity of curing water and total chlorides, calcium carbonate and calcium hydroxide leaching out at 7, 28 and 90 days of age. The paper also discusses the relevance of these chemicals in compressive strength gain and formation of permeable voids.
