In the present day context utilization of natural resources is increasing day by day, which is a burden for future generations. Limiting the usage of natural raw materials and development of sustainable methodologies is needed in all aspects of construction activities. In this regard, manufacturing of cement requires large amount of limestone deposits, fuel energy and on the other hand cement manufacturing liberates carbon dioxide (CO2) into atmosphere. Liberation of CO2 results in global warming which leads to climatic changes. Hence there is a need to develop an alternative material superior to cement without compromising its properties. To address the above problem present study is focused on examining the usage of Limestone Calcined Clay Cement (LC3) as partial replacement to clinker to an extent of 50% in concretes. M 30 grade of concrete is considered for investigation with three types of binders (i.e. LC3, Ordinary Portland Cement (OPC) and Pozzolana Portland Cement (PPC). From the studies on strength and durability it is evident that the performance of LC3 concrete is better than OPC and PPC based concrete.
