In this study, ambient temperature curing artificial aggregate were developed by using crushed-stone sludge. In order to evaluate the mechanical properties, the artificial aggregate was tested on 7 items. Test results showed that the artificial aggregate mostly satisfied the basic requirements of normal aggregate. The concrete with the artificial aggregate made by weathered rock and granite sludge was tested on the compressive test and flexural test. From the test results, It is confirmed that the concrete with the granite artificial aggregate develope the higher compressive strength than the crushed rock aggregate and the concrete with artificial aggregate concrete have the lower elastic modulus and flexural strength than the concrete with crushed rock aggregate.
