目前在北京等大城市及胜利油田,盖一些高层楼房已经不用沉重的石子了,而是用一种名叫“陶粒”的来代替。盖好的楼房体重轻,地基承受的压力小。这些房子,冬天显得暖和,即保暖,把背靠到墙上也不会感到阴凉;夏天又显得凉快,即隔热,室外的高温不容易传到房里;噪音小,即隔音。据说它还有较好的耐火、耐腐蚀、抗震、防冻性能呢!在国外,例如美国1977年用它来建造113层的希尔斯大厦,楼体总重23万吨,仅比20层的北京饭店重4万吨。这种陶粒是什么制成的呢?它就是煤矿区的煤层顶板和底板及其附近的一种深灰色或灰黄色粘土岩。它不能作煤烧,也不能盖房子,坑道掘进时只好把它 At present, in large cities such as Beijing and Shengli Oilfield, some high-rise buildings are no longer covered with heavy stones, instead they are replaced by a name called “ceramics.” The built-up building is light in weight and the foundation is under pressure. These houses are warm in the winter, that is, they keep warm, and do not feel cool when they put their backs against the wall. They look cool in summer, that is, they are insulated. The outdoor heat is not easily transmitted to the room; the noise is low, that is, sound insulation. It is said that it has good fire resistance, corrosion resistance, seismic resistance, and antifreeze performance. In foreign countries, for example, the United States used it to build the 113-storey Sears Tower in 1977. The building has a total weight of 230,000 tons, which is only 20 stories higher. Beijing Hotel weighs 40,000 tons. What is this ceramsite made of? It is a kind of dark gray or grayish yellow clay rock on the top and bottom of the coal seam in the coal mining area. It can’t be coal burned, it can’t build a house, it has to be taken when tunneling
