Study On Self Compacting Concrete with Different Minerals as Admixture- A Review

Self-Compacting Concrete (SCC) is an advanced form of high-performance concrete that flows under its own weight and achieves complete compaction without the need for external vibration. The incorporation of mineral admixtures such as fly ash, Ground Granulated Blast Furnace Slag (GGBS), silica fume, metakaolin, and nano-materials has significantly enhanced the performance and sustainability of SCC. This review paper critically analyzes previous studies on SCC incorporating various mineral admixtures with respect to fresh, mechanical, durability, and microstructural properties. The findings indicate that mineral admixtures improve workability, long-term strength, durability, and reduce environmental impact by lowering cement consumption. However, several research gaps exist in areas such as mix design standardization, long-term durability, shrinkage behavior, and optimization techniques. This paper identifies these gaps and suggests future research directions for developing sustainable and high-performance SCC.
