This study explores the mechanical properties of lightweight concrete incorporating Autoclaved Aerated Concrete (AAC) aggregates a light weight aggregate extracted from ACC block made with blast furnace slag, cement and foaming agent. The research focuses on evaluating the durability and strength of M35 grade concrete by partially replacing natural coarse aggregates with ACC aggregates at 0, 5, 10, 15 and 20% levels aiming to identify the optimal mix that balances strength and durability, making it suitable for applications in the construction industry. The results suggests that replacement of 15% gives optimum results which are validated with available codal results and design equations.

This study explores the mechanical properties of lightweight concrete incorporating Autoclaved Aerated Concrete (AAC) aggregates a light weight aggregate extracted from ACC block made with blast furnace slag, cement and foaming agent.

The results suggests that replacement of 15% gives optimum results which are validated with available codal results and design equations.
