Usage of Waste Marble Powder for the Manufacture of Limestone Calcinated Clay Cement (LCCC)

Abstract

AbstractDay by day, the production of cement is increasing with the increase in demand for construction industries. In the process of cement manufacturing, a lot of carbon dioxide (CO2) is released into the environment, which creates a global warming problem. Limestone calcinated clay cement (LCCC) can be used to partially solve this problem. In the present paper, the use of waste marble powder to manufacture calcinated limestone clay cement has been discussed. LCCC is an advanced ternary mixed cement made from a low grade mixture of 30% calcined clay, 15% limestone, 5% gypsum, and 50% cement clinkers. This means that 50% of cement clinkers are to be replaced by additional cementitious substances, which are beneficial for reducing CO2emissionsduringcement production. In the present study, two types of cements were prepared, one contains LCCC, and another contains marble stone calcined clay cement MCCC (Marble Stone-15%, Calcined clay-30%, Gypsum-5% and Clinker-50%) and these cements are compared to fly ash-based pozzolanic portland cement (PPC) and grade 53 ordinary portland cement (OPC).Characteristics of the prepared cement samples such as physical and chemical were carried out and compared with OPC and PPC. Similarly, prepared cement’s compressive strength (CS) was taken on cubes of 70.7 mm and tested after 3, 7, and 28 days, and results are compared with OPC and PPC.KeywordsWaste marble powderLimestone powderCalcined claysStandard consistency testCompressive strength
