Abstract

This study investigates the thermal properties of Limestone Calcined Clay Cement (LC3) concrete that includes steel fibres under elevated temperatures of 100°C, 200°C, 400°C, and 600°C. LC3 serves as an eco-friendly substitute for conventional cement, providing lower carbon emissions and enhanced durability. In this research, concrete specimens incorporating LC3 and steel fibres (The volume of taken as 0.5%, 1%, 1.5% and 2% of cement) were subjected to a range of elevated temperatures. The parameters such as residual compressive strength, mass loss, surface changes and flexural were analyzed. The Scanning Electron Microscopy (SEM) images of Ordinary Portland cement (OPC) and LC3 normal concrete at 100oC and 600oC were studied. Results indicated that steel fibre reinforcement significantly improved the residual strength and structural integrity of LC3 concrete at high temperatures. The LC3 retained 10–15% higher strength than OPC at 600°C. These findings suggest that steel fibre-reinforced LC3 concrete can be a feasible option for structural applications where thermal resistance is critical, contributing both to sustainability and fire safety in construction.
