Abstract

A major problem faced by the construction industries nowadays are the management and the disposal of construction & demolition waste. Therefore the recycling of Construction and Demolition Wastes has long been accepted to have the possibility of conserving natural resources. In some European countries it is used for both construction and maintenance, particularly where there is a scarcity of natural aggregate. Since the overall performance of recycled aggregates is lower than the natural aggregates, its application is limited. In order to improve the surface quality of recycled aggregates, they are washed with water and diluted acid. Strength properties of the treated and untreated coarse aggregate were compared. The results indicated that the compressive, flexure and split tensile strength of recycle aggregate is found to be less than the natural aggregate.
