Assessment of Optimum Percentages of Chemical Admixture in Composite Self-compacting Concrete

High-performance concrete known as self-compacting concrete (SSC) may flow effortlessly under its own weight without the use of mechanical vibration. Due to its excellent qualities, including filling formwork and self-consolidating, it is frequently used in construction. The study's objective is to determine the ideal chemical admixture percentages for composite SSC. 40% of GGBS, 30% of GGBS, 20% of GGBS and FA, 15% of GGBS and FA, 40% of FA, and 30% of FA were replaced for various amounts of GGBS, FA, and cement. The Bureau of Indian Standards (BIS) SSC was examined for strength, flexural, and split tensile strength behaviours at various ages for varied cement replacement amounts, and the outcomes were compared to conventional SSC (100% cement). Armix-HyyeCrete PC 20 super plasticizer has been utilized to ensure workability while maintaining a steady water-binder ratio. To improve strength and durability, the paper's conclusion emphasized the significance of determining the ideal amount of chemical admixture in composite SSC. Doing so might potentially lower the cost of SCC and make it more commercially feasible for usage in construction.
