Abstract

Carbon emissions from cement manufacturing are reduced by partially replacing cement clinkers with supplementary cementitious materials (SCM). In this study, Limestone calcined clay cement (LC 3 ) was prepared by blending 50% of OPC-43 grade with 50% Limestone calcined clay- LC 2 (63.3 % of calcined clay, 31.7% of lime, and 5% of gypsum), Fly ash-based Pozzolana Portland Cement (PPC) and Ordinary Portland Cement (OPC) was used to compare the mechanical properties at the age of 7 & 28 days of curing for M-25 and M-50 grades of concrete. The specimens for the compressive strength test, flexure strength test, Modulus of elasticity test, and Bond test of concrete with reinforcement of 25mm diameter bars were prepared as per Indian standard codes. The results of the study showed that the LC3 had higher compressive strength values at the age of 7 days, which is substantiated by flexure strength, modulus of elasticity, and pull-out strength values, whereas at the age of 28 days, LC3, OPC, and PPC had similar strengths.
