In this study, marble dust (MD) generated by the marble cutting industries and crushed bricks (CB) have been used as a cement replacement materials. The properties of cement and mortar containing MD and CB were investigated. The volume expansion, setting time, compressive strength and flexural strength of the mortar were determined. The microstructure of the mortar was investigated using scanning electron microscopy (SEM). The setting time of the cements were retarded when the waste material replaced a part of the clinker. The inclusion of MD at replacement level of 8 % resulted in a reduction in the strength of the mortar. However, incorporation of the MD and CB in cement resulted in significant increase in the strength of the mortar compared to MD mortar. In conclusion, the use of MD in combination with CB as a replacement material in cement is promising. However, the full evaluation of these materials demands a thorough examination in areas related to their specialized properties, and also extending testing on concrete produced with these materials.
