Sand Extraction: 1. Introduction GreenFacts

2021-2-16  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.

Construction sand shortage leads to development of

Worldwide consumption of sand equates to around 40 billion t annually and, accounting for an estimated 30 billion t of this, construction has by far the biggest ‘sand footprint’. Applications include land reclamation and building road embankments, but perhaps most significantly fine aggregates such as sand are also an essential component of
