continents. Fine aggregate, a principal component and binding material in concrete, is of great demand in the current scenario. The river sand, obtained from the riverbeds, is the foremost source for the fine aggregate for decades. Over-utilization of the river sand has caused depletion of availability and increased the price [1].
