Do you know the advantages of machine-made sand?

With the reduction of natural sand and gravel, the market demand for sand and gravel aggregates is large. The number of infrastructure construction projects has gradually increased, and the demand for sand and gravel has continued to increase. So compared with natural river sand, what are the characteristics of machine-made sand? 1. Resources
     The market for natural sand is gradually shrinking, which undoubtedly has an impact on the sand and gravel market. The natural sand can be based on various waste resources, in line with the scientific development concept and the characteristics of conservation and circular economy management, and there are long-term responsible persons and fixed business sites.
2. Quality
     The quality of natural sand is easily unstable, resulting in a waste of resources. The machine-made sand source is fixed and the mechanized production method ensures the quality of the product is stable, adjustable and controllable.
3. Quality
     Machine-made sand has high surface energy and hydrophilicity, has a micro-gradation of less than 75µm, and has multiple mineral components to choose from. The particle stability can be adjusted, and the particle shape can also be improved.
4. Physical and chemical energy
     The axial compressive strength, static elastic modulus, impermeability, frost resistance, corrosion resistance of carbonized steel bars, shrinkage, creep and other mechanical and long-term durability properties of machine-made sand are equal to or slightly higher than those of natural sand concrete. Therefore, compared with natural sand, machine-made sand not only has a wide range of sources, but also has stable materials, easy manipulation and control, and good *, which can meet the needs of construction.
