Incorporating Demolition and Construction Waste as a Reused Concrete Aggregate

In a lot of countries, including India, the issue of demolition and building waste is an important issue for the environment. The misguided C&D waste disposal might contaminate the atmosphere, the soil, and water bodies as well as contribute to the depletion of natural resources. Every year demand of conventional aggregate increases at a rate of 6.2%. To address these problems, various countries have implemented recycling practices for construction and demolition waste. Recycling construction waste can help lessen the negative effect on the surrounding environment by reusing materials and minimizing the need for extracting and producing new resources. This research paper study is based on recycling of construction waste to reduce stress on environment. The primary aim of studying different properties of recycled concrete aggregate and performing various tests is to analyse its properties. Relating recycled aggregate concrete to conventional aggregate concrete, the strength obtained is 10–15% lower. Research studies on recycled concrete aggregate (RCA) focus on assessing its properties to ensure its suitability for various applications. Some of the properties that are typically evaluated include compressive strength, water absorption, density, abrasion resistance, and durability. These tests help determine the quality and performance of RCA and compare it to conventional aggregates. Studies showed conventional aggregate can be replaced up to 30–50% by recycled aggregate. This approach not only reduces the environmental impact but also offers potential cost savings, as recycled aggregates are often less expensive than conventional aggregates.
