This study evaluates the influence of Alccofine 1203 on concrete properties, with a focus on workability, density, compressive strength, flexural strength, and split tensile strength. The experimental findings highlight that incorporating Alccofine 1203, characterized by its finer particle size and reduced water demand compared to Ordinary Portland Cement (OPC), leads to enhanced concrete performance. Notably, a 15% partial replacement of OPC with Alccofine 1203 significantly improved workability, yielding higher slump values for both M20 and M25 grade concretes. Compressive strength tests revealed marked enhancements, with maximum strength achieved at 15% replacement. This improvement is attributed to the optimized particle size distribution of Alccofine 1203, which minimizes capillary voids and creates a denser, more cohesive cement matrix. Flexural strength increased substantially, with gains of 34.95% for M20 and 19.49% for M25 concrete mixes at the optimal replacement level. Similarly, split tensile strength exhibited significant enhancement, further reinforcing the mechanical benefits of Alccofine 1203. The study concludes that Alccofine 1203 is an effective additive for elevating concrete performance. By increasing density, reducing voids, and forming a robust internal CSH gel structure, it significantly improves compressive, flexural, and tensile strengths. These findings underscore the potential of Alccofine 1203 to advance sustainable and high-performance concrete applications.
