Natural aggregates may be derived from land- or sea-based deposits, from gravel pits or hard-rock quarries, from sand dunes or river courses.

Kathy Feick Sand, gravel and crushed stone are all considered to be aggregates. More simply, aggregates include grains or fragments of rock. They are a non-renewable resource which we benefit from daily, but rarely think about. The aggregate industry is Ontario’s largest natural resource industry, affecting almost every aspect of our daily lives.

Origin and Classification of Aggregates - Civil Engineering Forum
2018.5.21 In that sense, the aggregates can be classified into two main categories: natural and crushed. In terms of origin, rocks are generally classified as igneous, sedimentary, or metamorphic based on how the rocks were formed over long periods of geological time. All rocks originate as igneous rocks, which are formed through cooling

Cement - Wikipedia
Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.

At Y = $7,500, AE1 = $5,300 + 1,000 + 1,400 − 200 = $7,500. A reduction of net exports of $1,000 shifts the aggregate expenditures curve down by $1,000 to AE2. The equilibrium real GDP falls from $7,500 to $5,000. The new aggregate expenditures curve, AE2, intersects the 45-degree line at real GDP of $5,000.
