PROPERTIES OF RECYCLED AGGREGATE CONCRETE

the University of Hong Kong recommend that the amount of recycled aggregate in structural concrete should range from 20% to 30%, in order to ensure that the maximum water absorption of aggregate used is less than 5% [6]. It is known that the aggregates from domestic natural resources have negligible absorption, up to
