Sustainable Concrete Made from Recycled Aggregates

The growing construction sector is responsible to leave behind construction and demolition (C&D) wastes, which has raised the concern about its dumping and adverse effect on environment. Mostly these wastes are used in landfills, but it is not a proper solution to clean this mess. Therefore, the beneficial utilization of these C&D wastes in concrete will not only help in waste management but also in resource management. The present study is carried out by replacing coarse aggregate by recycled aggregate. Coarse aggregate is a major constituent which occupies large volume along with fine aggregate in concrete. But the increasing usage of coarse aggregate in concrete production has alarmed the deterioration of natural resources. In this study, workability and mechanical properties such as compressive and flexural strength, of concrete prepared from recycled aggregate. Obtained results is used to conclude the effect of recycled aggregate in concrete.
