Investigation on Sandwiched Wall Panel with Lightweight Concrete Using Bloated Clay

This research focuses on the development of lightweight sandwich wall panels using Bloated Clay Aggregate (BCA) as a partial replacement for coarse aggregate in M30 grade concrete. The study evaluates mechanical properties such as compressive strength, split tensile strength, and flexural behavior. The use of BCA reduced the weight of concrete, improved workability, and enhanced ductility. The optimum performance was observed at 35% BCA replacement, proving it suitable for prefabricated and sustainable wall systems.
