The chemical composition of the gravel and sand is determined by the natural composition of the seam and cannot be changed by wet processing. The most important chemical grade indicator of sand and gravel is the content of SiO2. Depending on the target product, only quality silica sand can be used, with the content of SiO2 between 93% (refractories), 97% (foundry sand) and 99.9% (glass sand

Fine sand has grain sizes of > 0.063 – 0.2 mm, while medium sand is defined as > 0.2 – 0.63 mm and coarse sand as > 0.63 – 2.0 mm. Smaller grain sizes below fine sand are referred to as silt, even smaller sizes below 0.002 mm as clay. Larger grain sizes than coarse sand are called gravel or chippings (from the crushing of natural stone). Gravel sizes are also subdivided into fine, medium

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.

Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away. The more resistant quartz eventually is ground down in
