Fine and Coarse (Sand and gravel) Aggregates are divided into two distinct categories — fine and coarse. Fine aggregates generally consist of natural sand with most particles passing through a #4 sieve. Coarse aggregates are any particles greater than that, but generally range between 3/8 and 1.5 inches in diameter.

What is Aggregate? Aggregate is a term used for the collection of granular material that is used throughout the building industry. Aggregates refer to materials like gravel, sand, crushed stone, and recycled concrete. These materials make up the primary element in construction mixes like concrete and asphalt.
Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl 2017). Extremely low per-
Sand is a fine aggregate consisting of small granules of mineral particles. It is commonly used in concrete production, mortar, plastering, and as a bedding material for paving stones. The size of sand particles can vary, and different types of sand, such as river sand or crushed sand, may be used depending on the specific application.
The mode of deposition of sand and gravel is most commonly derived from the action of water in rivers, lakes or oceans. The water velocity and turbulence, combined with the settling rate of the particles, determine the movement of sand and gravels by suspension (sweeping free of the stream bed), saltation (bouncing), or traction (rolling, sliding or …
Sand and Gravel. Sand deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.

Sand and Gravel. Sand and gravel are unconsolidated, granular mineral materials produced by the natural disintegration of rock caused by weathering. The terms sand, gravel, clay and silt relate to grain size rather than composition. Sand is material passing through a number 4 (4.76 mm) sieve and remaining on a number 200 (74 µm …
