This report explores the concept of using waste materials as aggregate in concrete as a novel waste reuse strategy to minimize waste generation from construction sites. It discusses the utility of this concept, focusing on materials like recycled concrete, plastic particles, and crushed glass. The report explains how these materials can be used as substitutes for traditional aggregates, detailing the mixing process and the variations in percentages of different components to achieve the desired concrete mix. It highlights the benefits of this approach, such as reducing waste and the impact of using glass as a sand substitute, while also acknowledging limitations like decreased compressive strength and tensile strength when using recycled aggregates. The report concludes that while there are challenges, the overall concept offers a promising avenue for sustainable construction practices.
