Investigation on Properties of Self Compacting Concrete with Recycled Aggregate
Abstract
The use of recycled fine aggregates (RFA) obtained from construction and demolition waste offers a sustainable alternative to natural sand in self-compacting concrete (SCC). This study experimentally evaluates the influence of 5% and 10% RFA replacement on the fresh, mechanical, and durability properties of SCC designed for M35 and M45 grades. All mixes satisfied SCC workability requirements with slump flow values between 681 and 718 mm, V-funnel times of 8.1–10.7 s, and Lbox ratios above 0.85. Mechanical testing showed negligible strength reduction (~1%) at 5% replacement, while about 6% reduction was observed at 10% replacement after 28 days. Water absorption increased slightly but remained within acceptable limits (
