Properties Of High Strength Concrete Utilizing Recycled Aggregate.

      Аннотация: Globally, the utilization of concrete particularly high-strength concrete has been increasing day-by-day due to rapid industrialization and infrastructural developments. An enormous quantity of natural coarse aggregate is required for making concrete to meet the huge demand. The natural resources of coarse aggregate are depleting rapidly all over the world and urgently need to be conserved. On the other hand, millions of tonnes of construction and demolition (C&D) wastes are being generated from different sources. Therefore, in the present work, an experimental attempt has been made to utilize the recycled coarse aggregate from C&D waste to the maximum possible extent for producing the high-strength concrete. It obviously solves the problems associated with disposal and environmental impacts of C&D waste and will help conserve the natural resources of aggregates.
