The Hidden Environmental Toll of Mining the World’s Sand
Marine sand is less good for concrete, however, because it has to be washed clean of salt that could otherwise corrode metal in structural building reinforcements. That makes river sand the source of first resort — even though mining it is, according to the environmental group WWF, usually the most environmentally destructive.

HOW TO CHECK QUALITY OF SAND ON SITE? | CivilRead
Sand bulks the concrete and helps to increase the workability of concrete. Sand is formed by the weathering of rocks. Well, different regions use the variety of sands (Pit sand, River sand, Sea Sand) in construction according to the availability. A good fine aggregate used in construction should be well graded (all particles that have almost

Use of Quarry Dust to Replace Sand in Concrete – An
natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures.
