This paper conducts both experimental studies on high-strength concrete (HSC) incorporating the development of SCC mixes using industrial products such as Alccofine as an additive of 10% and GGBS as a partial replacement for cement at 0, 10, 20, 30, 40, 50, 60%, and the second phase covers the study of fresh and hardened properties of developed high strength SCC mixes in the laboratory. The study comprehensively tested properties like Rheological, compressive strength, and split tensile strength at 7, 28, and 91-day curing periods. The results highlighted enhanced workability when GGBS replaced cement, particularly in the 40% is optimum strength is satisfied. However, beyond 10% alccofine additive, adverse effects were observed across all parameters.
