Effect of High Temperature on the Calcinated Clay-Limestone Cement Concrete (LC3)
In cement manufacturing, a lot of CO2 emitted into the atmosphere creates a global warming problem. To solve this problem partly, calcined clay-limestone cement concrete can be used. The impact of high temperature on calcinated clay-limestone cement concrete (LC3) is studied in this paper. LC3 is innovative ternary mixed cement made from a mixture of 30% low-grade calcined clay, 15% limestone, and gypsum 5 percent, along with 50% cement clinkers. That means 50% of cement clinkers are replaced by supplementary cementitious materials which is advantageous for reducing carbon dioxide (CO2) emissions during cement manufacturing. In the present study, M25 grade concrete are prepared by calcined clay-limestone cement. After 28 days, prepared samples were subjected to 100, 200, 400, 600, and 800 °C temperature. The surface texture and compressive strength (CS) tests were performed on the cubes of size 100 × 100 × 100 mm3. The result displays that the CS after 200 °C decreases rapidly, and after ‘400 °C,’ major losses take place. Once the temperature touched 400 °C, minute visible cracks began to appear on all the grades of cube surface. All test results were compared with concrete prepared by ordinary Portland cement (OPC).
