Gravel Extraction - an overview ScienceDirect Topics

Because it is needed for so many construction purposes in such large volumes, sand and gravel extraction is a widespread activity along river channels throughout the world, especially close to growing urban areas. In locations distant from bedrock and glacial deposits, fluvial deposits may be the best or the only source of aggregates. In-stream and floodplain mining can be a small-scale activity using

uses of sand and gravel extraction

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. This production represents enough concrete to build a wall 27 metres
