Utilization of Demolished Concrete and Construction Waste as Coarse Aggregate in Concrete
Keywords:
Demolished, Concrete, AggregateAbstract
In the global construction industry, utilizing construction and demolition waste as a substitute for coarse aggregate is crucial for conserving natural resources and offers economic benefits. Currently, environmental concerns are of paramount importance, prompting efforts to enhance the use of construction and demolition waste in building projects. This approach presents a promising alternative to natural coarse aggregate. In laboratory settings, construction and demolition waste has been tested as a replacement for natural coarse aggregate in the production of concrete cubes and beams. These specimens were cast and subsequently evaluated for compressive and flexural strength after curing periods of 7, 14, and 28 days. The findings demonstrate that construction and demolition waste can effectively serve as a partial replacement for natural coarse aggregate up to 15 percent, without compromising the design strength.
