The Difference Between Manufactured Sand, Natural River Sand, Mountain Sand, Sea Sand and Desert Sand

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.

Influence of Manufactured Sand of Different Production Processes on Concrete Performance

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.

Spare Parts in Vertical Shaft Impact Crusher

The main spare parts in vertical shaft impact crusher (sand making machine) are feeder hopper, raw material screen, crushing cavity, impeller, bearing, transmission shaft and so on. Among them, transmission shaft and bearing mainly transport power, impeller and crushing cavity are the main parts to process raw material.

Factors Affecting the Crushing Efficiency of the Crusher

During the production process of rock crusher, the crushing efficiency is not only affected by its performance, but also affected by several other factors. Knowing the factors affect stone crusher crushing efficiency can help investors improve the production rate. In the following part, we focus on factors affect the production efficiency of rock crusher.

Mineral Admixtures on Concrete

Used to improve the performance of concrete, industrial waste or mineral fine powder with a certain degree of fineness added in the concrete mixing process, it is an auxiliary cementing material that replaces part of the cement consumption.

How to Process Concrete Admixtures

To give full play to the pozzolanic activity, morphological water reduction effect and micro-aggregate filling effect of active admixtures and inactive admixtures, and improve the quality and performance of concrete, admixtures must have a finer particle size and larger than cement Specific surface area.

How to Choose the Process of Manufactured Sand? Wet or Dry

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.
