RECYCLED CONCRETE AGGREGATE AN ALTERNATIVE CONCEPT An alternative concept for the recycling of concrete waste is to recover clean unbound coarse aggregate from the concrete matrix This paper describes a programme of investigations into aggregate liberation which resulted when concrete specimens were subjected to compressive failure enacted through staged size reduction using Evaluation of the embodied energy requirement in mechanical recycling of CFRP was calculated by using a Overflow Ball Mill which is size of 18ft × 22ft that operates in closed circuit with a classifier at a 250 circulating load The type of ball inside of the
