Abstract
This study explores the use of recycled concrete aggregate (RCA) in M20 grade concrete, focusing on the effects of RCA substitution on the material's properties. Various percentages of RCA (0%, 10%, 20%, 30%, and 100%) were tested to assess their impact on compressive strength, workability, and durability. Results show that compressive strength decreases with increased RCA, but a 10% replacement maintains acceptable performance. Workability decreases with higher RCA content, though adjustments can improve it. The study demonstrates the potential of RCA as a sustainable alternative for M20 grade concrete. The rising demand for natural aggregates in the construction industry has led to the depletion of natural resources and increased environmental concerns. This study explores the feasibility and performance of M20 grade concrete by partially replacing natural aggregates with recycled aggregates derived from construction and demolition waste. The experimental investigation evaluates the mechanical and durability properties of concrete mixes with varying percentages of recycled coarse aggregates.
