The impurities like clay and silt in sand can reduce the strength of concrete by weakening the bond between the cement and aggregates. This can lead to an increase in voids in the concrete mixture, reducing its structural integrity and overall durability. It is important to use clean and well-graded sand to maintain the desired strength of the concrete.
