Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials. 0%. Since it is artificially manufactured.
