Description Aggregates are granular materials, that arent organic, with a natural source such as sand, gravel, crushed stone or artificial source such as blast furnace slag, expanded perlite and expanded clay, which are gathered together by means of a binding agent consisting of cement-water mixture in concrete production. Aggregate has a very important place in concrete production in economic and technical
Coarse Aggregate Crushed stone is created through the mining and crushing of rock. The rock is crushed into several different graded sizes for use in applications including ready mix concrete, asphalt and decorative stone. Gravel is created by river erosion, resulting in smooth and rounded products.
Mar 01, 2017 Aggregates are coarse particulate rock-like material consisting of a collection of particles ranging in size from 0.1 mm to 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and synthetic aggregate. Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing
Coarse aggregates are any particles greater than 0.19 inch, but generally range between 38 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.
