Abstract In this research, the simultaneous effect of marble waste dust (MWD) and magnetized water (MW) on the fresh, hardened and durability properties of mortar mixes were investigated. A total of 10 mortar mixes using different cement replacement ratios of MWD (0%, 10%, 20%, 30 and 40%) with regular tap water (RTW) and MW were prepared and tested. The standard consistency and setting characteristics, dry density, compressive and tensile strengths, water absorption and resistance to the acid attack of specimens were examined. The results showed that the fresh, hardened and durability properties of mortar mixes were improved by using MW. The results also revealed that the mortar mixes with either RTW or MW and 10% MWD as cement replacement displayed the most improvement in the hardened and durability performance compared to other mixes. However, using higher amounts of MWD leads to a lower strength and durability performance of the mortar mixes due to more porous microstructure.
