Abstract:
Every year, India produces a massive amount of debris from construction and destruction. The disposal of garbage has become problematic since these waste products require a huge space to be dumped. Furthermore, the ongoing depletion of natural resources in the manufacturing of traditional concrete raises the price of fine and coarse aggregate and reduces their availability. Thus, there is expanding interest in the potential application of using demolition debris to create coarse aggregate through recycling building sector. Beyond the environmental benefits of reducing the demand for land for waste disposal, recycling demolition wastes can contribute to the conservation of natural resources. Evaluation of recycled coarse aggregate's mechanical, physical, and long-lasting qualities is crucial when using it in structural concrete. To determine whether to use concrete using recycled coarse aggregate (RCA) as structural concrete, its mechanical and physical qualities must be examined. The goal of the current investigation is to evaluate concrete that has had all its NCA completely replaced with RCA. Additionally, the mechanical and durability test results are assessed and contrasted with NCA concrete. The high percentage of water absorption in RCA concrete is the primary issue. Like natural coarse aggregate concrete, RCA has a high compressive strength. This is mostly because the recycled coarse aggregate has a lot of mortar on to its surface and the RCA is highly angular, which results in coarse aggregate of low quality. The experimental investigation results indicate that RCA's high percentage of water absorption property qualifies it for usage as structural concrete in specific applications.
