Abstract

Due to the rapid urbanization, the demand for infrastructure such as housing, road, transportation, water supply & sanitation has increased rapidly. In this scenario, the recycling of Construction and demolition wastes prove to have the possibility to conserve the use of natural resources and also leads to reduction in energy consumption. The recycling of aggregate and its use in construction technology gives sustainable & economical results, particularly where there is a scarcity of construction aggregate. In this paper, the durability of recycled aggregate concrete & its importance has been discussed with the help of various research works. Various research has been done to compensate for the lower quality of the recycled aggregates. Using aggregates obtained by crushing and sieving concrete cubes, the analysis of recycled concrete aggregates on some durability related properties were determined. The behaviour of recycled aggregate concrete under various durability tests such as sorption test, chloride-ion penetration test etc., has been investigated. With the incorporation of mineral admixtures like GGBFS, flyash the durability studies made and the optimum amount of these admixtures for maximum performance has been illustrated.
