Abstract
The sludge produced from marble processing has become a significant environmental hazard in major marble mining and processing countries. Utilizing marble dust (MD) as a partial replacement for cement offers benefits: it reduces the need for landfill disposal, which can lead to air and water pollution, and it decreases the consumption of cement, which contributes to the global carbon footprint. This study examines the key properties of concrete incorporated with MD and develops a composite mix with the optimal MD content using response surface methodology. The influence of MD/Cement ratio, Water/Cementitious material ratio, and parameters indicating important constitutive elements in MD, i.e., CaO/MD ratio, on the compressive strength were analyzed. Findings indicate that increasing the MD/Cement ratio from 0.564 to 0.667 results in an approximate 16% reduction in compressive strength. As anticipated, the Water/Cementitious ratio has a more pronounced effect on compressive strength compared to the MD/Cement ratio.
