The compressive strength and the flexural strength increased with the increase in the percentage of quarry dust, but there was a reduction in the strength beyond 30% of quarry dust. Therefore, it can be concluded that the optimum percentage of red mud and quarry dust for the partial replacement of cement and sand was 15% and …

Low-cost quarry dust is utilized in a variety of studies to test its influence on expansive soil stabilization. After adding quarry dust and running several tests, the UCS increases as the proportion of quarry dust increases. When the proportion of quarry dust is increased, MDD increases but OMC declines.
