The current study presents an investigation into the optimal content determination of the mix parameters in their acceptable ranges through various fresh, mechanical, and durability characteristics along with microstructural analysis of the ground granulated blast furnace slag (GGBFS)-based SCGC cured under ambient temperature. Ordinary Portland Cement (OPC)-based self-compacting concrete (SCC) was prepared too as a control concrete. Both the M25 SCGC and SCC were characterized through fresh property tests satisfying the flowability, passing ability, and segregation resistance. The mechanical...
