Advantages of Sand and Gravel Aggregate
 

Cost-Effectiveness

One of the significant advantages of material sand and gravel aggregate is their cost-effectiveness. They are widely available in most regions and can be sourced locally, minimizing transportation costs.

Durability and Strength Factors

Sand and gravel aggregate contribute to the durability and strength of structures. In concrete, the combination of sand and gravel creates a solid matrix that adds strength to the material.

Recyclable

Sand and gravel aggregate can be recycled and reused, further decreasing their ecological footprint. By implementing recycling processes, the environmental impact of sand and gravel extraction can be significantly reduced, leading to a more sustainable construction industry.

Versatile

One of the more versatile common types of aggregate you can find is sand. Traditional building sand is generally used for housing developments and building structures. It is also used in bricklaying and mortar, pointing applications and other general construction work.

What Systems are Generally Composed of Sand and Gravel Aggregate Production Lines?

Feeding System: Generally, a vibrating feeder is used to be responsible for the supply of stone;

Transportation System: The belt conveyor is responsible for the transportation of materials between different equipment;

Crushing System: This is the core of the entire production line, which generally consists of multiple crushers. Its function is to crush various ore raw materials to the required particle size;

Screening System: It includes circular vibrating screen and linear vibrating screen.

 

Application of Sand and Gravel Aggregate

 

Concrete Preparation

In concrete, sand and gravel aggregates occupy most of the volume and are used to provide strength and structural stability to the concrete.

Road Construction

Sand and gravel aggregates are used as paving materials in road construction, including the base and surface layers of roads.

Building Construction

In construction, sand and gravel aggregates are used in the manufacture of building materials such as blocks, prefabricated elements, bricks, and as part of the foundation, walls and roof of a building.

Infrastructure Construction

Such as bridge construction and tunnel construction also require large quantities of sand and gravel aggregates as building materials.

Railway Engineering

Sand and gravel aggregates are often used for the bedding underneath railroad tracks, which helps to spread out the loads borne by the railroad tracks while providing stable support.

Water Engineering

In the construction of dams, embankments, harbors and ports, sand and gravel aggregates are used as an important ingredient in concrete or for filling to increase the stability and durability of the structure.

Landscaping

Selected sand and gravel aggregates are widely used in outdoor landscaping, such as the decoration of sidewalks, courtyards, and flower beds, due to their natural color and texture.

Environmental Projects

Gravel aggregates are also used in certain environmental projects, such as as filtering materials in rainwater collection and filtration systems to help remove pollutants.

Decorative Use

Specific types of aggregates, such as colored gravel, can be used for indoor and outdoor decoration to provide a beautiful visual effect.

 

Advantages of Steel Slag and Slag Treatment
1

Sustainability

Reusing slag reduces the need for virgin materials, making construction more eco-friendly. This helps in conserving natural resources and reducing the carbon footprint of construction projects.

2

Economic Benefits

Repurposing a byproduct offsets the costs of disposal and can even generate revenue. Additionally, slag often proves more cost-effective than some traditional materials.

3

Enhanced Durability

Some applications, like road construction, benefit from the high durability and wear resistance of steel slag.

4

Improved Concrete Properties

When used in concrete, slag can increase the final product's durability, reduce permeability, and provide greater long-term strength.

 

Process of Steel Slag and Slag Treatment
 

Steel Slag Crushing
After the initial crushing by a jaw crusher, the steel slag is reduced to a size smaller than 60 mm.

 

Steel Slag Grinding
In this step, we utilize a steel slag rod mill to grind the crushed steel slag, ensuring uniformity of the final product.

 

Steel Slag Separation
Steel slag separation typically employs magnetic separation, aiming to extract useful iron metals from the slag.Both steel particles and iron powder in the steel slag exhibit magnetism.

 

Particle Classification
Using a vibrating screen to sieve metal iron particles of various sizes allows for the classification of steel particles and iron powder into coarse, medium, fine, and ultrafine grades, depending on the product's intended application.

FAQ
 

Q: What is the role of sand and gravel aggregate in concrete production?

A: Sand and gravel aggregate can provide good stability, wear resistance and durability to concrete. Moreover, it can also play the role of reducing shrinkage, inhibiting crack propagation, and reducing heat of hydration. Adding as much aggregate as possible to concrete can reduce the cost of concrete without affecting its properties.

Q: What is the boundary size between sand and gravel?

A: Gravel: particle sizes from 4.75 to 75 mm; Sand: particle sizes from 0.075 to 4.75 mm; Fines: particles smaller than 0.075 mm (silt and clay).

Q: How to sand and gravel aggregate on site?

A: All kinds of sand and gravel aggregates need to be stored on hard and flat ground, preferably as level as possible. The ground of the storage space should be clean and dry, with retaining walls used to separate the different aggregates.

Q: What is the best method to compact sand and gravel aggregate?

A: Plate compactors are best suited to the compaction of bituminous and granular materials e.g. granular soils, gravels and sands or mixtures of both. Cohesive soils such as silt and clay are best compacted using the impact force produced by an upright rammer.

Q: What do sand and gravel aggregate remove?

A: Sand filtration is used for the removal of suspended matter, as well as floating and sinkable particles. The wastewater flows vertically through a fine bed of sand and/or gravel. Particles are removed by way of absorption or physical encapsulation.

Q: Is steel slag good for anything?

A: Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage.

Q: How is steel slag produced?

A: It is formed when molten steel reacts with fluxes during the steelmaking process, separating impurities and leaving behind a solid residue.

Q: What are the environmental benefits of slag treatment?

A: Processing and utilizing slag in various applications like road construction so that the risk of these by-products being sent to landfills is reduced, which in turn helps reduce creating an environmental hazard.

Q: How is slag treated?

A: In the ladle treatment station, the slag is heated and purged/stirred with gaseous reduction media. Fluxing and the addition of solids is also possible. During operation, the liquid metal droplets, which are entrapped in the slag, grow as a result of the stirring and enhanced coagulation effects in the stirred melt.

Q: How is steel slag recycled in the steel industry?

A: This nonmetallic slag material can either be crushed and screened for aggregate use (steel slag aggregates), or sintered and recycled as flux material in the iron and steel furnaces. Steel slag aggregates generally exhibit a propensity to expand.
