当今我国石膏储量居世界首位,石膏资源丰富,但与国外相比,石膏在墙体材料中的利用率却很低,仅占全部墙材的20％。如轻质砌块现产量约600万m~3,而石膏砌块仅为10万m~3左右。但有关行家认为随着我国墙体材料的不断创新,石膏砌块将大力发展,其原因一是石膏砌块作为轻质 Nowadays, China ranks first in the world in its gypsum reserves and its gypsum resources are abundant. However, compared with foreign countries, the utilization of gypsum in wall materials is very low, accounting for only 20% of all wall materials. For example, the output of lightweight blocks is about 6 million m 3, and the gypsum block is only about 100,000 m 3 . However, experts believe that with the continuous innovation of China’s wall materials, gypsum block will be vigorously developed, the first reason is that the gypsum block as a lightweight
