An Experimental inquiry into Concrete Properties with Partial Cement Replacement Using Alccofine and Metakaolin

In this research work, we delve into the pivotal role of concrete in modern construction practices and its indispensable nature across diverse structures. Concrete’s widespread use underscores its significance in the construction industry, where economic considerations heavily rely on material cost efficiency. This study focuses on experimental investigations involving Alccofine and metakaolin, aimed at enhancing concrete strength while concurrently addressing environmental concerns such as CO2 emissions. These materials serve as substitutes for traditional cement in M20 grade concrete, with meticulous mix designs tailored to optimize performance. Metakaolin replaces cement at varying percentages (0%, 5%, 10%, and 15%), while Alccofine remains a constant 10% replacement in cement concrete. Specimens undergo rigorous curing and are subjected to comprehensive 28-day testing for compressive, split tensile and flexural strengths. This investigation aims to provide insights into the feasibility and effectiveness of using Alccofine and metakaolin as sustainable alternatives in concrete production, thus addressing both economic and environmental considerations.
