Performance studies on limestone calcined clay based concrete

Abstract

In the construction field, lot of improvement in sustainable development is going on from last few decades, mainly use of pozzolanic materials are increasing day by day for the production of cement. On the other hand a lot of anthropogenic CO2 gas is liberating in to atmosphere while manufacturing cement. To alter the emission of CO2, use of alternative cementious materials is one of the best practices like fly ash, rice husk ash, GGBS and Metakaolin. Due to the use of such materials there is a lag in early strength development in concrete. Hence there is need to develop a substitute material for cement without negotiating in properties. In the present paper Limestone Calcined Clay Cement (LC3) as an alternative to Ordinary Portland Cement (OPC) is examined for strength and durability and the results are compared with Portland Pozzolana Cement (PPC) for M 50 grade of concrete. From results it is found that the use of LC3 concrete is beneficial in terms of strength and durability.
