Aggregate" is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete).

Soil-cement (SC) is an engineered, densely compacted mixture of soil/aggregate, portland or blended cement plus, sometimes, other cementitious materials, and water. SC looks like regular soil when mixed, but when compacted, the cement binds the soil particles together, making it stronger and more durable.
Aggregates, both fine and coarse, constitute about 60 -80% of the concrete formula. Mixed together with cement and water, the aggregate element helps make concrete more compact, provide strength, durability and workability. These properties make concrete one of the most widely used materials across the world.

Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.
1. The concrete mix is workable.It can be placed and consolidated properly by yourself or your workmen. 2. Desired qualities of the hardened concrete are met: for example, resistance to freezing and thawing and deicing chemicals, watertightness (low permeability), wear resistance, and strength. Know what you are trying to achieve with the concrete.

A. Aggregate is granular material, such as sand, gravel, crushed stone, crushed hydraulic cement concrete, or air-cooled iron blast-furnace slag, used with hydraulic cement to produce either concrete or mortar. It is divided into two groups by size, as coarse aggregate (material retained on the 4.75-mm (No. 4) sieve), and fine aggregate ...
Old, unneeded concrete can be recycled and used to create recycled aggregate.
