Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
Sand and gravel deposits and bedrock may be mined or quarried to produce raw materials known as aggregate. Aggregate is necessary to manufacture concrete, asphalt, and other products. These products are the building blocks for our homes, businesses, roads, and bridges. Certain types of rock may be used as decorative stone. The United States produces about 17.6 billion dollars'

Industrial minerals include construction aggregate (sand, gravel and crushed stone), peat, kaolin clay, dimension stone, landscape stone, and silica sand. Aggregate mining operations occur in nearly every county in Minnesota. Aggregate materials are the essential elements of a variety of construction products, such as concrete.
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.
Gravel is a mixture of three sizes or types of material: stone, sand and fines. This will be discussed further in the next section.Without a good blend of these three sizes, the gravel will perform poorly. Unfortunately, poor performing gravel will often be blamed on the maintenance operator. But the operator cannot make good gravel out of bad ...
