Four advantages of machine-made aggregates

With the increasing decline of natural sand and gravel, the aggregate market is gradually booming. Especially with the increasing number of infrastructure projects, the demand for sand and gravel continues to increase, and there is even a trend that demand exceeds supply. Compared with natural river sand, what are the advantages of machine-made sand?

Resource advantage

Natural sand mining is self-evident to the environment, and it is a non-renewable development model in the long run. On the other hand, driven by environmental protection policies, the natural sand market is gradually shrinking, which undoubtedly has an impact on the sand and gravel market. Natural sand can be based on various waste resources, in line with the scientific development concept and the advantages of saving and recycling economy management, and it has long-term responsible persons and fixed business sites.

Quality advantage

The quality of natural sand is easy to be unstable, which causes a waste of resources. The machine-made sand source is fixed and the mechanized production method ensures that the product quality is stable, adjustable and controllable.

Character advantage

Machine-made sand has high surface energy and hydrophilicity, complete gradation, micro-gradation less than 75μm, and multiple mineral components to choose from. The particle stability can be adjusted, and the particle shape can also be improved.

Physical and chemical energy advantage

The axial compressive strength, static elastic modulus, impermeability, frost resistance, corrosion of carbonized steel bars, shrinkage, creep and other mechanical and long-term durability of machine-made sand are equal to or slightly higher than natural sand concrete. Therefore, compared with natural sand, machine-made sand has a wide range of sources, stable material, easy manipulation and control, good performance, can meet construction needs, and is economically feasible. It is the development direction of the future construction market and is also very beneficial to natural environmental protection.
