Abstract: Stone cutting industry produces slurry waste that causes environmental pollution problems and its disposal is controlled. In addition stone cutting slurry can improve concrete mix properties such compressive and tensile strength when add at proper amounts. In this research, we investigate the impact of adding different fractions of cutting slurry waste on important concrete properties. To analyze slurry impact several levels are added and tested. Concrete and mortar samples were prepared with 25, 50, 75 and 100% of water esults shamount. Standard laboratory methods are used to analyze compressive, flexural and tensile strength. Row that adding slurry waste has improved slump test performance and to improved compressive, tensile and flexural s t rength up to 50% of slurry addition. A robust trend of increasing workability is observed with increasing slurry fraction.
