Review of Self Compacting Geopolymer Concrete Using Slag Sand as Fine Aggregate

The manufacture of ordinary Portland cement produces a lot of CO2s in the atmosphere. The production of cement emits approximately 5% of worlds carbon. Carbon dioxide emissions from the cement industry are a major environmental concern, which is increasing day by day searching for an alternative replacement for cement has become very important. Self-compacting concrete (SCC) offers advantages in complex formwork and congested reinforcement, but its reliance on Portland cement raises environmental concerns. Geopolymer concrete is an eco-friendly construction material that utilizes industrial by-products such as fly ash, ground granulated blast furnace slag, rice husk ash, and metakaolin as binders. Recycling these waste materials for construction offers a sustainable solution to environmental concerns and presents a cost-effective building alternative. This review explores the potential of integrating the self-compacting properties of SCC with the sustainability of GPC by using slag sand as a fine aggregate. It examines key aspects such as workability, mechanical strength, durability, and microstructure of SCC-GPC incorporating slag sand. Additionally, it highlights the challenges, existing research gaps, and future research directions in this area. Developing new construction materials from industrial waste contributes to a more sustainable future by providing an environmentally friendly and resource-efficient alternative in the construction industry. The literature on geopolymer concrete which is based various industrial wastes such as fly ash, copper slag etc… replaced by natural resource in geopolymer concrete This study provides a review of research era in the field of Self compacting Geo polymer concrete
