Enhanced Involuntary Characteristics and Corrosion Resistance for Reclaimed Materials

This contemporary review presents an in-depth analysis of Portland Pozzolanic cement, the predominant material employed in concrete production. The construction industry’s substantial consumption of cement necessitates an exploration of alternative materials to mitigate environmental pollution caused by high carbon dioxide emissions and the depletion of raw materials, mainly limestone. This study uses silica fume (SF) and ground granulated blast furnace slag (GGBS) as cement substitutes to lower the price of concrete and cement consumption rates. Fractional substitution experiments are used in the study to look at the strength characteristics of GGBS and SF. GGBS, a byproduct of the steel manufacturing industry, is derived from separating molten steel from impurities. M25 grade concrete is employed. GGBS substitution levels of 30, 35, and 40% are compared with PPC, determining the optimal GGBS percentage. Keeping GGBS optimum content constant, 5, 10, and 15% of SF are substituted with pure cement. After preparing specimens, curing is performed for 7 and 28 days, followed by tests including split tensile, flexural, and compressive strength assessments, revealing that the highest strength is achieved when 35% of GGBS and 10% of SF replace cement. This study provides valuable insights into applying GGBS and silica fumes in concrete production, contributing to sustainable practices and efficient material utilization in the construction industry.
