The present test method covers the determination of the particle
size distribution of fine and coarse aggregates by screening.
Some aggregate specific cations that reference this method contain
grading requirements that include both coarse and stone aggregate
fractions. Instructions for the granulometric determination of said
aggregates are included.

The division of soil into different fractions, selected by the size of its
component particles, is called gradation distribution of a soil; The
particles of each fraction are characterized because their size is
between a maximum value and a minimum value, correlatively for
the different fractions in such a way that the maximum of a fraction
is the minimum of the one that follows it correlatively.
In coarse soils (gravel, sand, and non-plastic silt), with a simple
structure, the most important characteristic to deï??ne its resistance is
compactness; The angle of the grains and the orientation of the
particles also play an important, although minor, role.
One of the reasons that have contributed to the spread of gradation
techniques is that, in a certain sense, the gradation distribution
provides a classiï??cation criteria. The well-known terms clay, silt, sand, and
gravel have this origin and a soil was classified as clay or sand depending on whether it had this or that maximum size. The need for a soil classification system is not debatable, but the engineer must look for one in which the classification criteria are useful.

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.

Stone Aggregate

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.
