A CRITICAL EVALUATION ON POZZOLONIC PROPERTIES OF SELECTED MATERIALS AND THEIR REPLACEMENT IN CEMENT

Increase in population in the country is demanding more and more infrastructure projects and housing which intern is demanding more and more cement manufacturing. This is resulting in releasing of huge amount of CO2 into the atmosphere which is causing environmental problems. There is a need to look for alternative materials which lessen emanation of green house gasses. As a piece of this various alternative materials to cement have been explored by various researchers. In the present study it is focused on basalt, fly ash, metakaolin, tank sediments, sludge of vitrified ceramic tile plant, clayey soil and clay deposits. Published articles related to the pozzolonic materials are collected and complied.
