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.
Boiler bed materials are made out of quality refractory aggregates of high alumina contents & of highly dense texture. Boiler bed material is ideal for obtaining perfect fluidization in boilers of Circulating fluidized bed combustion (CFBC) & fluidized bed combustion (FBC) boilers.
Boiler bed material of low ferric high temperature product is passed through high power magnetic separation process to eliminate free iron particles.
It is an appropriate product to sustain technical properties for fluidizing at high
temperature up to 1400 C under most critical working situation.
We offer finest refractory crushed boiler bed material of higher quality.

Our reputed company is widely involved in supplying a wide range of Aggregates. The commercial production of aggregates was initiated with the aim of catering to the overall building, construction and the infrastructure development community that uses aggregate as the critical raw material. With its contractual as well as commercial aggregate mining spread across Gujarat.
We serve the best quality of Aggregate all across the nations. Aggregate is composed of various particles used in construction as foundation. It includes sand, slag, stone and gravel etc. The aggregate that we offer acts as reinforcement to add strength to the overall composite material which gets used for constructions. The product that we offer goes through the quality inspection process. We offer this product at reasonable price range.
Aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application
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.
Laira Group will deliver high-quality aggregate in a range of sizes to our valued clients, based on their needs.
It consists of a mixture of materials between fine and coarse aggregate that allows the material to be within the granulometry curves that mark the norm SCT and AASHTO.
Granite is a types of felsic intrusive igneous rock that is granular and phaneritic in texture. Granite is being Crush into Different Diameters for the purpose of Aggregate in Concrete.
The size range of various coarse aggregates given below:
Fine gravel: 4mm 8mm
Medium gravel: 8mm 16mm
Coarse gravel: 16mm 64mm
Cobbles: 64mm 256mm
Boulders: > 256mm
