Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.

When configuring concrete, coarse and medium river sand should be preferred for fine aggregate. The fineness modulus of desert sand is usually less than 1.5, and the finer one has a modulus less than 0.7, which is ultra-fine sand. Concrete that uses desert sand alone will consume a large amount of cement, reduce strength, and weaken frost

Sand is the finest aggregate. It comes in different gradations: sharp sand, builder’s sand, and kiln-dried silver sand, which vary from coarsest to finest, respectively. Finer sands are a good aggregate for mortars and grouts. Coarser sands are also a popular aggregate for concrete mixes. [3] GRANITE

Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.
