A STUDY ON RECYCLED CONCRETE AGGREGATES

The recycled aggregate concrete is made by mixing 60% of recycled aggregates with 40% of crushed stone chips. The aggregates used for concrete batching are maintained at saturated surface dry condition. The workability of the recycled aggregate concrete is slightly lower than that of the conventional concrete.

The Environmental Impact of Recycled Concrete

Abstract Concrete is a building material used worldwide and consumes large amounts of raw materials. The concrete structure is cheaper than steel structures; the raw materials can be found in almost anywhere and can be moulded easily. Nevertheless, the concrete industry produces a lot of waste and the old concrete many times goes to landfills. The aim of this work is identify, in a critical ...
