Exploring the opportunities for reuse of municipal Construction and Demolition (C&D) wastes in concrete

The sustainable practices in the built environment are based on conservationof resources, such as minimum use of material, energy and water. disposal of constructionwaste poses major challenge to the municipal administration of the developing countries.the fast urbanization and rapid construction in these countries has generated substantialvolume of construction wastes. there are many options for the disposal of constructionwastes. one of such options is to utilize these wastes as aggregates for concrete. the reuseof such aggregates in the concrete would reduce the disposal costs of construction wasteson one hand and burden on natural resources in terms of resource harvesting on the otherhand. in this research work, the construction wastes collected from the municipal sourceshave been segregated, graded and utilized as aggregates in cement concrete. consideringdierent percentages of recycled aggregates, various concrete mixtures were prepared andtested to determine their compressive strengths for evalauating suitability of the concretemixtures for construction purposes. the test results indiacte that the recycled aggregatescan be used for producing plain concrete mixtures for mass concreting and construction ofpavements and walkways.
