HomeSand In The Desert
Recent years, with the decreasing of river sand resources and the protection policies of the government, the investment capital of river sand for construction is getting higher and higher. In this case, more and more investors start to turn their eyes of artificial sand. But artificial sand making equipment is relatively expensive. so many customers wonder why cannot we use sand in the desert for construction field. In this article, we mainly introduce reasons why not use desert sand in construction field.
Why Not Use Sand In The Desert For Construction
In the following part, we mainly introduce why not use sand in the desert for construction from several aspects, such as fineness, gradation, transportation cost, deformability, efflorescence etc.
Fineness
Sand in the desert is very fine. The smaller the particle size, the bigger the total superficial area. In concrete, the surface of sand is wrapped up by cement paste. In this case, the bigger the total superficial area, the more cement paste is needed. So fine sized sea sand will obviously increase the investment cost.
Efflorescence
Sands in the desert are under long time sunshine and efflorescence, which makes the sand contains relatively more impurities. To use sands in the desert, customers need firstly separate the impurities out. This will also increase the investment cost.
Deformability
Sands in the desert have bad deformability. As we know, construction buildings, especially high-rise buildings require sand with great deformability to ensure the quality. If we use sands in the desert in construction field, with its bad deformability, the buildings are not firm and durable. So we do not suggest sands in the desert for construction.
Transportation Cost
Another important reason is the transportation cost. We all know that deserts are generally far away from urban area. If we want to use sands in the desert, we need to transport them out from the desert. The transportation cost is very high. In this case, the investment cost is also increased.
Gradation
The gradation of sands in the desert is single. But in construction field, we generally need sand with different gradations to build various buildings. Sands in the desert cannot meet this requirement.
From the above information, we can see that even there are abundant desert sand resources in the world, but they are not really suitable for construction field. While choosing suitable sand or other raw materials, investors should take various factors into consideration to ensure the quality of the buildings.
