Sand and gravels are naturally occurring, in pits, while crushed rock is a product of blasting and crushing rock, in a quarry.
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

Normal Concrete refers to the fresh concrete which haven't yet cured providing that there was no add mixtures/any accelerators being infused upon mixing fine aggregates, gravel and cement plus water.
Pumiscrete has been used in buildings for many years. It is concrete that uses crushed volcanic rock rather than conventional sand and gravel
Ans: Aggregate is the component of a composite material used to resist compressive stressOR1. 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.
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.
