ABC is also known as aggregate base course. This product is mainly use for back filling, road construction etc. ABC gravel typically contains stone that is no larger than 1 to 1.5 inches. Larger stone (3-inch) has more strength to support heavy logging equipment. ABC and 3-inch crusher run gravel contain a high percentage of fines (gravel dust) that add no more strength to a road than the soil beneath it.
Metal aggregates,3/4 are irregular in shape, are an important material used in the production of concrete products, which provide much needed strength to concrete. Most 3/4 metals are used for construction purposes, mainly as aggregate with or without a binder. Road base or road surfacing material, as well as Rail Road Ballast #5, are the major uses without a binder.
This is a feasible fine aggregate and filler material for replacing fine natural aggregate in concrete production and similar to river sand in terms of density, gravity, grain size, and chemical composition. Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
Stone chips, termed “chip metal” in construction parlance in Sri Lanka, constitute one of the main construction materials along with bricks, sand, cement, and steel. Chip metal is bit small than metal ¾ . This product is mainly used for concrete products, and for construction of buildings.
Due to the fast-growing construction industry demand, manufactured sand (M sand) is an alternative to river sand. M -sand differs from natural river sand in its physical and mineralogical properties. This is a aggregate base product, which mainly use for concrete, wall constructions etc.
Plastering sand has finer particles than sharp sand or manufacturing sand. This means it can be used, effectively for internal and external wall rendering and plasterwork. Mainly used for plastering works of the construction.
ABC Filling typically contains small stones and is used for filling purposes. The ABC filling gives more strength to a road than the soil beneath it.
