In recent years, the price of China’s sand and gravel market has continued to rise, which directly affects the progress of project construction. What caused the tight supply of sand and gravel? There are 3 main reasons for the increase in the price of sand and gravel.

Manufactured Sand Wet Process
There is no restriction on the mud content of the masterbatch.
The mud content of the finished material is low and stable, and the methylene blue value is easy to control and stable.
The surface of manufactured sand is clean.
The dust from sand making and washing is easy to control.
Manufactured sand is a kind of artificial sand, which can control the stone powder content and gradation requirements in accordance with the national standards and technical requirements of project quality, which can effectively meet the actual needs of different projects.
Sand is the main component of modern building concrete and can be divided into artificial sand and natural sand. Artificial sand is divided into manufactured sand and mixed sand. Natural sand can be divided into mountain sand, river sand, desert sand and sea sand. This article will analyze the difference between manufactured sand, natural river sand, mountain sand, sea sand and desert sand.
The workability, compressive strength, splitting tensile strength, compressive modulus of elasticity and carbonization resistance of concrete prepared with dry-processed manufactured sand (M-sand) are better than those of ordinary manufactured sand. In the case of little difference in workability, dry-process manufactured sand can save the amount of water-reducing agent, and manufactured sand produced by different production processes has the same effect on the electric flux of concrete.
The common manufactured sand process is divided into wet process and dry process. Since the dry process appeared later than the wet process, and the dry process was developed on the basis of the traditional wet process, there may be people I feel that the wet method may not have more advantages than the dry method in terms of process.
