Natural Colour Aggregates

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 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 aggregate is a broad category of coarse 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.

Crushed stone or stone or angular rock is a construction aggregate. It is created by mining a suitable rock formation and then using a crusher to break down the stone into different sizes. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of weathering and erosion.
Crushed stone has continuously been used for a variety of construction needs because of its versatility. It is one of the most common and accessible natural resources on the planet. It is one of our most abundant and basic of raw materials.

Coarse and fine aggregates, suitable for use in bituminous paving mixtures, consist of hard, tough, durable natural river rocks shall be processed, by crushing, screening, and washing into S1, 3/4, 3/8, and G1. At the time of delivery, the aggregates shall not contain injurious amounts of foreign materials such as clay, loam, wood, metallic contents, unhydrated lime, or other deleterious materials. The physical requirements conform to are grading and fineness modulus, soundness, degradation, expansion, friable particles, stripping, adherent coatings, crushed count, and environmental stability.

3/4 Stone chips aggregates, often referred to as 3/4-inch aggregates, are a type of construction aggregate characterized by their approximate size of three-fourths of an inch (20 mm aggregates) in diameter. These aggregates are commonly used in construction and various civil engineering applications. Here are some key details about 3/4 Stone chips aggregates:
1. Size: As the name suggests, 3/4 Stone chips aggregates have a particle size of roughly 3/4 of an inch in diameter. They are sometimes also referred to as 20 mm aggregates in metric units.
2. Composition: 3/4 Stone chips aggregates are typically made from crushed stone or naturally occurring stone materials, such as granite, limestone, trap rock, or gravel. The specific type of stone used can vary based on regional availability and project requirements.
3. Uses: These aggregates have a wide range of applications, including:
Construction:3/4 Stone chips aggregates aggregates are commonly used as a key component in concrete mixes, asphalt mixes, and road construction. They provide stability and strength to these materials.
Drainage: Their size and angular shape make them suitable for use in drainage systems, French drains, and other applications where effective drainage is needed.
Landscaping: 3/4 Stone chips aggregates can be used in landscaping projects for pathways, decorative features, and as a base for retaining walls or pavers.
Subbase: They are also used as a subbase material for foundations and roads, providing a stable foundation for construction.
4. Durability: 3/4 Stone chips aggregates are known for their durability and ability to withstand heavy loads and wear over time. They contribute to the overall strength and longevity of construction projects.
5. Installation: Proper installation techniques, such as spreading and compacting the aggregates to achieve the desired thickness and density, are essential to ensure their effectiveness in construction and drainage applications.
6. Cost: The cost of 3/4 Stone chips aggregates can vary depending on factors like location, the specific type of stone used, and local market conditions and the availability of aggregates supplier. They are generally cost-effective compared to other construction materials.
In summary, 3/4 stone chips aggregates are a versatile and widely used construction material valued for their size consistency, durability, and suitability for various applications, 3/4 stone chips aggregates supplier are playing key factor to boot this business in Bangladesh.
