Coarse Aggregates
* Coarse Aggregates are the primary building material supply, which includes a core component of constructions and high durability in strength. The Coarse Aggregates are the crushed stones extracted from crushing large rock quarry, boulders, or gravels (larger size). And the majority of the coarse aggregates constitute crushed gravels or stones.
* They normally range 40mm, 20mm, 14mm, and 10mm aggregates. While 20mm size aggregates are commonly used, whereas the aggregates greater than 40mm size are used in mass concreting.
Aggregates Process
* Aggregates are processed to segregated coarse and fine aggregates, properly cleaned, and removed from other materials to give desired strength. Some aggregators are crushed, while some are screened and washed. The proper coarse aggregates processing will furnish cleanliness, sanitation to prevent contamination and maintained to upgrade the quality.
Coarse Aggregates Applications
* Concrete production is the main use of coarse aggregates. It is available in Stone Chips and Cone Crushed. A mixture of concrete is applied for different civil engineering construction products including:
Asphalt Concrete
Road Words
Portland Cement Concrete
Masonry and Paving Blocks
Leisure and Sports Facilities
Foundations
Plaster
Mortar, etc.

Quality
* The quality of coarse aggregate influences the concrete's durability, which is a significant part of the selection process. Particular shape and size influence strength and workability. The coarse aggregates are tested to determine the properties and characteristics which are based on grading, abrasion, and skid resistance test, crushing value, etc.
Transportation
* Coarse aggregates are transported through in the barges or vessel fleets to different destinations across the globe. The designated fleet conveyor will transport coarse aggregates not less than 10mm, 20mm, 40mm in diameter with a density not less than 2 metric tons. Coarse Aggregates are supplied in loose cargo or jumbo bags. They are also shipped in bulk packs, not less than 1 ton each.
Aggregates are inert granular ingredients, such as sand, gravel, or crushed stone, which, along with water and Portland cement, are an important component in concrete. Which is classified into two distinct categories, Fine and Coarse.
Fine aggregates normally consist of natural sand or crushed stone with most participles passing through a 3/8inch sieve.
Coarse aggregates are any particles larger than 0.19 inches but usually range between 3/8 and 1.5 inches in diameter.
Aggregates must be pure, hard, and strong particles that are free of absorbed contaminants, clay coatings, and other fine materials that could cause concrete to deteriorate.
