According to the abstract released by the Intellectual Property India: "Partial Replacement of Cement With GGBS in Concrete Abstract The growing demand for sustainable construction materials has intensified research into the partial replacement of Ordinary Portland Cement (OPC) with Ground Granulated Blast Furnace Slag (GGBS) in concrete. GGBS, a by product of the iron and steel industry, possesses latent hydraulic properties that contribute to enhanced mechanical and durability characteristics of concrete while significantly reducing environmental impact. This study investigates the performance of concrete mixes incorporating varying percentages of GGBS as a partial substitute for cement. Concrete specimens were prepared with different replacement levels of cement by GGBS and evaluated for workability, compressive strength, split tensile strength, and durability parameters such as water absorption and resistance to chemical attack. Experimental results indicate that partial replacement of cement with GGBS improves workability due to its finer particle size and smooth texture. While early-age strength shows a marginal reduction, concrete containing GGBS exhibits comparable or superior strength at later ages due to the continued pozzolanic and hydraulic reactions. Additionally, GGBS-based concrete demonstrates improved durability, reduced permeability, and enhanced resistance to sulfate and chloride attacks, making it suitable for aggressive environmental conditions. The reduction in cement content also leads to lower carbon dioxide emissions, contributing to eco-friendly and sustainable construction practices. The study concludes that the partial replacement of cement with GGBS is an effective approach to producing durable, economical, and environmentally responsible concrete without compromising structural performance."
