The hybrid cement mix achieved compressive strengths of 35.5 MPa after 28 days and 40.8 MPa after 90 days, showing strong performance.
A blend of 15% OPC, 15% CSA, 35% FA, and 35% GGBFS compared favorably to a 50:50 OPC–CSA mix, implying effective use of alternative materials.
Cement hydration was tested with sodium sulfate and sodium hydroxide, confirming the impact of alkaline activation on strength development.
Hybrid systems reduce CO₂ emissions in construction, highlighting the potential for environmentally-friendly alternatives.
