• Concerning acid attack, and in HCl solution, the mortar with marble waste sand had a bad resistance to aggression due the high amount of CaCO3 in marble. On the other hand, marble sand enhances resistance to H2SO4.

In light of the analysis, the conclusion of this study is that the introduction of marble waste sand was beneficial to some properties and durability of mortars.
