Why can't desert sand be used directly in the construction industry?
With the rapid development of economy, the demand for sand in the construction industry has increased, and the supply is in short supply. Why can't we directly use the sand in the desert as engineering buildings? Wouldn't this not only solve the desert, but also make use of the sand? In fact, there are many reasons why the desert sand is not used by us.
Desert sand density is not up to standard
Now we build houses or repair roads with river sand, because the density of river sand is very high, and easy mixing river sand with cement and other building materials, but the desert sand not work because its density is very small, too thin, smooth and not sticky. If you use the desert sand to pave the road, it will surely crack soon.
Desert sand can only be used after washing
The desert sand cannot be used directly. If you want to use it, you must first wash the desert sand before you can use it. This is a laborious thing, and no one wants to do it. Therefore, thery would rather use cheap river sand or machine-made sand than desert sand.
Desert sand components too complicated
Not all the sand in the desert is sand. It may also contain heavy alkaline soil. It is very difficult to select. If it is not selected properly, it will corrode the steel bars in the constructure structure. If used in high buildings, it is easy to cause collapse, let alone withstand natural disasters such as typhoons and earthquakes.
Obviously, desert sand cannot be used directly in construction, but there is currently a kind of stone that can replace river sand, that is, machine-made sand! Machine-made sand refers to sand that is processed by a sand making machine and other ancillary equipment. The finished product is more regular and can be processed into sand of different sizes according to different technological requirements, which can better meet daily needs.
The cost of natural sand mining is getting higher and higher. After years of continuous mining, natural sand resources are rapidly declining. In some areas, natural sand has been exhausted or nearly exhausted. In order to protect river dikes and dams and protect the ecological balance, mining is strictly prohibited.
Limited by these reasons, the cost of natural sand is getting higher and higher, while its profit is getting lower and lower, and the market is getting smaller and smaller. Therefore, machine-made sand is becoming more and more popular in the market, and its market share is getting higher and higher. In the future, machine-made sand will become an important sandstone to replace river sand.
