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 billion to billion tonnes a year for 2012 alone. This production represents enough concrete to build a ...

fine aggregate (sand less than 5 mm diameter) and coarse aggregate (gravel 6 – 20mm diameter). When mixed together in the correct proportions they produce a dense material. Water is added to the mix to react chemically with the cement to make it harden and to make the complete mixture easy to move and place where required. The fine and coarse aggregates provide most of the bulk and strength ...
