It is found that recycled coarse aggregate are reduced to various sizes during the process of crushing and sieving (by a sieve of 4.75mm), which gives best particle size distribution. The amount of fine particles (4.75mm) after recycling of demolished were in the order of 5-20% depending upon the original grade of demolished concrete.
