various researches conducted on the utilization of waste products in concrete in order to reduce the utilization of natu-ral resources. Khaloo (1995) investigated the use of crushed tile as a source of coarse aggregate in concrete. The crushed tile had a lower density and a much higher water absorption value compared to those of natural crushed
