Due to the rising need for high strength/high performance concrete, alternatives to cement as a binding medium are becoming more and more important and then can be met by use of Supplementary cementitious materials (SCMs). To lower the cement content and give concrete more strength, these SCMs will be partially replaced which leads to smaller pore sizes densifies the pore structure which improves properties. In comparison to cement-only control concrete, this study examines the effects of SCMs including Metakaolin (MK), Flyash (FA), and Nano silica (NS) when employed in quaternary blends. The samples of size 150 x 150 x 150 mm was casted and tested at different temperatures of 2000C, 4000C, 6000C, 8000C, and 10000C for a duration of 4 hrs, 8 hrs & 12 hrs in an electrical bogie hearth furnace and compared with samples tested at room temperature. Studies included colour change, spalling, weight loss, and residual compressive strength. At 2000C, specimens' compressive strengths are nearly identical to those evaluated at room temperature; however, at 4000C, it was shown that, during a fire lasting four hours, specimens' residual compressive strengths increased by as much as 15.61% for quaternary blended concrete and 3.67% for control concrete, respectively. The residual compressive strength of concrete specimens exposed to temperatures beyond 6000C significantly decreased, and the lowest residual strength of about 10% at 10000C for a length of 12 hours for both quaternary blended and control concrete was observed at this temperature. Results showed a larger loss of compressive strength with longer exposure times at the same temperature. It was found that quaternary blended concrete had a higher residual compressive strength than control concrete, making it more fire resistant than control concrete.
