Abstract: Limestone calcined clay cement (LC3 ) is a new type of cement blended with 15% limestone,50% clinker,5% gypsum and 30% clay. The production of LC3 can reduce CO2 emissions up to 30% as compared to that of OPC. The utilization of calcined kaolinite clay as alternative material for bond is a choice to relieve the ecological effect. In this work, Mechanical properties of LC3 like fineness, consistency, initial and final setting time, compressive strength with different clinker proportions (40%, 50%, 60%) at different calcined kaolin clay (40%, 30%, 20%) at a temperature 450ºC were studied by casting mortar cube specimens and concrete cubes were tested and the results were compared with strength of OPC mortar and concrete cubes. For durability study of LC3 concrete, LC3 and OPC concrete cubes were exposed to chloride attack (NaCl) and sulphate attack (MgSO4) and the results were compared.
