STRUCTURAL PERFORMANCE OF SUSTAINABLE CONCRETE WITH RECYCLED AGGREGATE MATERIALS

Abstract

The construction industry is a major consumer of natural resources and a significant contributor to environmental degradation. Sustainable construction practices are therefore essential to reduce resource depletion and environmental impact. The use of recycled aggregate materials in concrete offers an effective solution for sustainable development. This paper presents an eco-sustainable concrete mix design incorporating recycled aggregates derived from construction and demolition waste. The study evaluates the mechanical, durability, and environmental performance of recycled aggregate concrete. Different replacement ratios are investigated to determine optimal mix proportions. Experimental results indicate that recycled aggregates can be effectively used without significant loss in strength. The proposed mix design reduces carbon emissions and promotes resource conservation. The findings support the feasibility of recycled aggregate concrete for sustainable construction.
