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. Technical Specifications Name Description Product Name - Coarse Aggregates Type - Aggregates, Crushed Stones, Stone Chips Material - Gabbro , Granite Aggregate Strength - 5.5-7 MPa Applications - Construction, Landscaping, Paving, Foundations, Walkways, Railway Embarkments, Road Metal Packaging Type - Loose Cargo 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.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.
