Geological mass
In the Earth sciences, aggregate has three possible meanings.
In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles.[1][2] Examples are dolomite, which is an aggregate of crystals of the mineral dolomite,[3] and rock gypsum, an aggregate of crystals of the mineral gypsum.[4] Lapis lazuli is a type of rock composed of an aggregate of crystals of many minerals including lazurite, pyrite, phlogopite, calcite, potassium feldspar, wollastonite and some sodalite group minerals.[5]
In pedology, an aggregate is a mass of soil particles. If the aggregate has formed naturally, it can be called a ped; if formed artificially, it can be called a clod.[6]
In the construction industry, an aggregate (often referred to as a construction aggregate) is sand, gravel or crushed rock that has been mined or quarried for use as a building material.
Construction aggregate examples
[edit]
Aggregates are used extensively in the construction industry.[9][10] Often in making concrete, a construction aggregate is used,[4]
with about 6 billion tons of concrete produced per year.[11]
