Fine aggregate is a construction material that is typically made up of natural sand or crushed stone, with particles that are smaller than 0.2 inches in diameter. It is one of the two main types of aggregate used in concrete production, the other being coarse aggregate.
Fine aggregate is used to fill the voids between the larger coarse aggregate particles in concrete, and to improve its workability and finish. Fine aggregate is also used in the production of mortars, grouts, and other construction materials.
The quality of fine aggregate is important for the strength and durability of the final concrete product. Fine aggregate should be clean, well-graded, and free of contaminants such as clay, silt, and organic matter.
