In this research, Crushed-stone sludge obtained from production processing of crushed aggregates were recycled to manufacture artificial aggregate. Compressive strength , Elastic modulus, Splitting strength, Flexural strength and freeze/thaw, Carbonation test were conducted for artificial aggregate concrete. The results showed that compressive strength and freeze/thaw and depth of carbonation resistance of concrete using crushed-stone sludge aggregate were higher than those of concrete using normal crushed stone. but elastic modulus, splitting and flexural strength were lower than those of concrete using normal crushed-stone
