Aggregates

Aggregates are mixtures of sand, gravel, crushed rock or other bulk minerals used in construction, principally as a component of concrete, and in civil engineering. At CEMENTATION we supply aggregates for a range of core applications, from fill materials to aggregates that can be used in concrete, precast concrete, asphalt and for surface dressing. Aggregate plays an important role in concrete and construction part. We supply quality material which makes durable concrete with higher compressive strength and low permeability having better finish. We can supply a wide range of coarse, fine and blended aggregates in accordance with international standards.

We acquire rock mines and stone crushing plants and enable us to fulfil contract of any size. Progressive stages if crushing and screening enable us to produce a range of aggregate sizes (06mm to 65mm)

APPLICATIONS

Road and Highway surfaces
Constructions or Civil work
Railway Ballast
To make Concrete or Asphalt
Filling

Aggregates

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

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 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.
