Abstract
Trash from the construction industry, namely construction and demolition (C&D) debris, is dumped rather than disposed of, which adds to the depletion of the natural resources necessary to produce concrete. Recycling and reuse of these C&D wastes can help protect the environment and consume fewer natural resources. However, the quality of RA is significantly impacted negatively by cement mortar that is put to the surface of the aggregate, which results in greater porosity and higher rates of water absorption. This study will look at the properties of concrete that contains demolition waste that has been processed in different ways. Abrasion therapy (AT), cement slurry treatment (CST), and chemical treatment (CT) are examples of therapeutic techniques under investigation. Laying the foundation for the use of reactive aggregates (RA) in structural concrete is the aim of this study. It examines the physical and mechanical characteristics of natural materials and RA while testing concrete compositions with various ratios of fine and coarse RA. Results demonstrate that abrasion treatment (AT) provides greater comp. strength compared to alternative RAC and is more effective and efficient. For higher grades of concrete with varying ratios of coarse and fine RAs, the toughened characteristics of RAC were further examined.The findings demonstrated that a partial replacement with a 30% coarse RA and a 50% fine RA achieved comp. strength equivalent to NAC.
