2018-4-3 material for partial replacement of sand in concrete for modifying its properties. In the concrete mixes sand was replaced at 5%, 10%, 15%, 20% and 25% by weight and effects of replacement on concrete is observed. Use of saw dust in concrete permits disposal of waste (saw dust) and make concrete light in weight.

2021-6-4 investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

2020-8-1 They have found that it is possible to replace river sand partially in concrete (Prabhu et al., 2015, Siddique et al., 2009). This partial replacement also varies with respect to the physical and chemical properties of WFS which influence the characteristics of a concrete to a greater extent (Monosi et al., 2013). The study on the investigation and reuse of waste foundry sand not only provides better utilization of waste
