Performance Evaluation of Adhession in Recycled and Reused Construction Material in RCC

In order to produce aggregate of acceptable quality, the concrete salvaged from demolition sites may be utilised, which minimises the need for natural aggregate and, in turn, lowers the construction industry's ever-growing prices. Additionally, it conserves energy consumed in production. Therefore, utilising aggregates from recent demolition activities, the current effort entails a comprehensive examination of the characteristics of concrete in both its fresh and hardened states. Concrete created from destroyed concrete is compared to concrete made from natural aggregate in terms of its qualities (Compressive Strength). In the current study, recycled aggregate has been used as a substitute for natural coarse aggregates in various ratios of 0%, 25%, 50%, 75%, and 100%. Studying numerous characteristics, like as compressive strength, is part of it. When building roads, recycled materials are utilised as the granular foundation course. When utilised as a granular base course for roads, recycled aggregate outperformed natural aggregate. The recycled gravel derived from crushed concrete is frequently used for foundational work, base and sub-base course construction, and paving purposes. Recycled aggregate has a slightly lower compressive strength than original concrete (up to 20% lower in certain circumstances). The use of particles from destroyed concrete has a major negative impact on workability but no discernible impact on compressive strength.
