Also called natural sand, river sand is categorized as fine sand and is usually found near streams and river banks. The softness of river sand allows for its usage in concrete and masonry work. River sand is also ideal for plastering, RCC, and several other block works. The main caveat with river sand is that it tends to have high silica …
