With the ongoing urbanization and the rise of tall buildings, the construction industry has become an important industry today. The reason why it is important is because tall buildings are where people live, so what does the construction industry use to build the most houses? They are usually made with dry mortar, which can be both aesthetically pleasing and strong, so why is it strong? Dry mortar in the end with what things to do it? With all these questions, we go to study the mystery and problems about the dry mortar!

Dry mortar is from the 1950s European construction market development and growth, now in Germany, Austria, Finland and other countries will be dry mortar as the main mortar materials, only Germany has an annual output of 100,000 tons of more than 200 factories, an average of every five hundred thousand people have a dry mortar production enterprises. In Asia, Singapore, Japan, South Korea, Hong Kong and other places of dry mortar development is also very rapid, we are also China, since the nineties, most of the construction companies have used dry mortar, of which we in Guangzhou City, Guangdong Province, to promote the use of dry mortar promotion of six years, a lot of norms have gradually changed.

Why is it that the norms for mortar in Guangzhou have become strict? First of all, a variety of raw materials (including cement, sand, lime paste, etc.) storage site, will have an impact on the surrounding environment. Secondly, more dust will be formed in the process of mortar mixing. As the relevant data show, the construction dust in Guangzhou city accounts for about 22% of the dust emission in the urban area, while the cement use and its related total dust emission accounts for about 35% of the total construction dust in the urban area.

The disadvantages of polluting the environment to a minimum, and thus famous, so that more people choose dry mortar, dry mortar specification of the two most important points, one is the conditions must be given priority to the use of dry mortar and ready-mixed mortar, the other is not allowed to mix mud with cement at the construction site, greatly reducing the damage to the environment.
