Abstract

Recycled aggregates are comprised of crushed, graded inorganic particles processed from the fabrics that have been applied in the constructions and demolition debris. The objective of this task is to find the force characteristics of recycled aggregates for application in high strength structural concrete, which will yield a fuller apprehension of the attributes of concrete with recycled aggregates, as an alternative material to coarse aggregate (NA) in structural concrete. The scope of this project is to find and compare the effectiveness of concrete by using different percentage of recycled aggregates. Recycled aggregate is also the case of artificial aggregate which is obtained from Construction and demolition (C&D) wastes. Constructions and demolitions are the procedures that work hand in hand. The demolished building rubble in India generally goes to waste in landfills. Recycling of these concrete waste materials from building demolition can provide a resolution to this problem. The probe was carried out using the sieve analysis test, Specific gravity test, Water absorption test, Impact test, Crushing value test, Workability test and compressive strength test. There were a total of six masses of concrete mixtures, consisting of every 20% growth of recycled aggregate replacement, from 0% to 100%.
