Ans: Aggregate is the component of a composite material used to resist compressive stress
OR
1. Forming a total. Gathering from various sources and considering as a whole.
2. Geology. rock fragments used in construction, ie. mixed with cement. (gravel)

1. General: Collective amount, sum, or mass arrived-at by adding or putting together all components, elements, or parts of an assemblage or group, without implying that the resulting total is whole (contains everything that should be in it).
2. Construction: Granular mineral material (such as sand, gravel, crushed stone) used with a bonding medium (such as cement or clay) to make concrete, plaster, or terrazzo mixture. See link below.
There are two different types of aggregates namely,Fine aggregates - size of the aggregate is less than 4.75 mmExample : SandCoarse aggregates - Size of the aggregate is more than 4.75 mmExample : Gravel
as we know we have sieve sizes. aggregates which got retained in 4.75 mm sieve size is known as coarse aggregates or we can say aggregates having size more than 4.75mm.
how does the fineness modulus of aggregate affect the strength of concrete
Examples of aggregates used in concrete works are,Gravel.river Sand.Quarry sand.Brick bats.Granular slag.poultry sand.Limestone Aggregate

ASTM D75 is the ASTM that covers the sampling of aggregates.
Raw materials that are a component in concrete, aggregates are inert granular materials such as sand, gravel or crushed stone. Coarse aggregates are particles greater than 4.75mm, but they generally range between 9.5mm to 37.5mm in diameter. Primary coarse aggregates come from the land or water. Secondary aggregates are the by-products of extractive operations. The third source coarse aggregates come from is recycled aggregate, which is sand, and recycled concrete aggregate.
as we know we have sieve sizes. aggregates which got retained in 4.75 mm sieve size is known as coarse aggregates or we can say aggregates having size more than 4.75mm.
Specimens of microcrystalline quartz are aggregates of microscopic crystals

Construction Aggregates Market is estimated to be US$ 313.12 billion by 2030 with a CAGR of 3.0% during the forecast period
The word "grading" refers to the diversity in size of the aggregates. Aggregates that have "good grading" or are "well graded" have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
