石膏是一种古老的无机胶凝材料。人们知道石膏能够做为胶凝材料使用,也是一个偶然发现。远古时代,人们发现由于雷击引起森林大火使石膏石加热分解, 遇大雨又能凝结硬化,于是,逐渐知道它可以利用因此,可以说在史前人类就已经利用石膏了。当然,这是极原始,极粗糙的使用。随着科学技术的进步和人们对居住条件的要求,石膏做为室内装饰装修材料在国外已有100多年的历史我国在建筑上应用石膏的历史可以追溯到修建西汉墓,长城用的
Gypsum is an ancient inorganic cementing material. People know that gypsum can be used as a cementitious material and it was also an accidental discovery. In ancient times, people discovered that as a result of a lightning strike, a forest fire caused the gypsum rock to decompose, and in the event of heavy rain it condenses and hardens. Therefore, it became known that it could be used. Therefore, it can be said that mankind had used gypsum in prehistoric times. Of course, this is a very primitive, extremely rough use. With the advancement of science and technology and people’s requirements for living conditions, plaster has been used as interior decoration materials for more than 100 years in foreign countries. The history of applying plaster on buildings can be traced back to the construction of Western Han tombs, which were used by the Great Wall.
