Abstract

Today construction industry faces shortage of aggregate. Construction industry produces 40% of total waste each year. This causes the severe environmental hazards and causes land fill issue. The possible solution is to reuse recycled concrete aggregate in place of natural aggregate, which reduces landfill disposal, conserving the primary resources and reducing the transportation cost and promote the sustainable development. Hence its need to study the structural properties of recycled aggregate concrete. Recycled aggregate are easily available and economical compared to other natural resources. Demolished structures, site tested concrete, pile cap demolished concrete are the good sources of recycled aggregate. In this paper various studies done by the authors is studied.
