Therefore, before using river sand in construction, it is advisable to check on silica content to ensure it’s below 5%. River sands also have high moisture content, which means it won’t require high amounts of water when used in construction. Manufactured Sand. Manufactured sand is a more sustainable alternative to river sand.

2021-7-30 Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
