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.

This approach enabled the researchers to link extraction, processing, distribution, economics and policy in order to gain a detailed …
IN MANY AREAS in Southern Africa river waters have an extremely high sediment load or turbidity. Numerous problems, and high costs, are associated with the abstraction and treatment of such waters. Problems include loss of storage through siltation, siltation of intake structures, rapid wear of raw water pumps and pipework, low throughput rates …
