There are two main types of sand used in modern engineering, natural sand and mechanism sand.Natural sand is sand and gravel particles polished by nature. Although the quality of natural sand is very good, it is a non-renewable resource.The emergence of mechanism sand has solved the current dilemma well.The use of mechanism sand is also a new direction for the future development of the sand and gravel industry, and it is imperative to replace natural sand with mechanism sand.

The advantages of mechanism sand are as follows：

1. Recycling and stable supply

Mechanism sand can be used to crush natural stones, used waste bricks and cement blocks. It can be said that mechanism sand is a recyclable resource with a wide range of raw materials.

2. The production of mechanism sand can be combined with the production process of gravel to reduce costs.

The production of mechanism sand can be controlled by adjusting the advanced equipment and technology for the production of mechanism sand to produce mechanism sand that meets the design needs of concrete compounding ratio. The grade is reasonable, the porosity is low, and the stability of the product is guaranteed, and the quality is easy to control.

3. The specific surface area of the mechanism sand is larger, and the concrete formulated with the mechanism sand has higher strength.

The particles of mechanism sand have many edges and corners, and the surface is rough. It is conducive to the bonding with cemented materials such as cement, and it is conducive to the improvement of the strength of concrete. From the surface, it also brings the disadvantage of poor ease, and the stone powder in mechanism sand can just make up for this defect.Moreover, stone powder can form a soft slurry with cement and other cemented materials and water, which increases the amount of slurry for the coagulation process and reduces the friction between sand and gravel, thereby improving the ease of concrete.

4. It is conducive to the comprehensive utilization of mineral resources and solves environmental protection problems

The application of mechanical sand in concrete has improved and alleviated a series of environmental problems caused by sand mining in ruined fields, reduced the production cost of commercial concrete and the price of construction sand, improved the quality of construction projects, and reduced the tension of construction sand. Pressure.Because the nearby material production mechanism solves the long transportation distance, saves national resources, reduces costs, and protects the environment.
