This research focuses on the development and assessment of self-compacting lightweight concrete conforming to IS codes. The concrete mix incorporates perlite powder as a pozzolan, leveraging natural perlite as both coarse and fine aggregates. The study encompasses a series of tests to thoroughly examine the concrete's properties and performance. Fresh properties evaluation includes measurements of slump, slump flow, unit weight, air content, and setting time, providing crucial insights into workability and consistency. Moving to hardened properties, the structural performance will be analyzed by assessing mechanical properties like compressive strength, splitting tensile strength, flexural tensile strength, modulus of elasticity. Furthermore, durability characteristics will be investigated through rigorous testing methodologies. The concrete's resistance to chloride ingress will be determined via rapid chloride-ion penetrability tests. Additionally, its resilience against aggressive chemical solutions—such as sulphuric acid, magnesium sulphate, and sodium bicarbonate—will be thoroughly examined. A comparative analysis will be conducted with conventional normal weight concrete to gauge the performance and superiority of the developed lightweight concrete. This comprehensive study aims to provide valuable insights into the viability and potential applications of self-compacting lightweight concrete in construction practices, emphasizing its mechanical strength and durability compared to conventional counterparts.
