Abstract

In recent years the demolition and construction activities is increased due to development of urban and industrial areas, which lead to production of large amount of waste and large utilization of natural resources. The over use of natural resources for new construction activities without going for alternative or recycling materials in future will leads to environmental concern and price increase in the materials and high demand for materials. Scarcity of natural coarse aggregate has initiated the use of recycled aggregate obtained from crushed concrete rubbles in building industry. The quality of recycled aggregate concrete (RAC) produced depends on the quality of recycled aggregate obtained from old concrete. Several methods such as acid treatment, thermal treatment, mechanical treatment, etc. are available to improve the quality of recycled concrete aggregate. This paper aims to compare the effect of treatment methods on the physical, mechanical properties of these aggregates, and their compressive strength.
