Theirefiore, ai studiy wias coniducited tio anailyze tihe quiality ofi thie Miusi riiver sand before and after washing with a sluice box and its use in the concrete industry. From the results of testing the quality of river sand before the washing process, the mud content obtained an average level of river sand of 7.5% (does not meet SNI standairds).
