The research addresses the feasibility of substituting different cements without compromising the desired strength, particularly in ready-mix concrete scenarios where material shortages may occur.

For compressive strength, OPC 42.5N demonstrated the highest strength, with OPC 52.5N following, and PFA 32.5N and PLC 32.5N trailing at both 7 and 28 days. By 56 days, OPC 52.5N showed a slightly higher compressive strength than OPC 42.5N, while PLC 32.5N and PFA 32.5N remained lower than those of concrete prepared with OPC cements. Temperature tests revealed that PLC 32.5N reached its peak temperature the quickest, followed by OPC 52.5N, PFA 32.5N, and OPC 42.5N.
