我国页岩墙材应重点发展“三高”烧结制品

我国页岩砖以实心砖和多孔砖为主 ,不仅产品单一 ,而且砖强度、外观、产品保温隔热等性能与发达国家相差甚大。文章就我国页岩砖发展方向提出了建议 ,认为我国未来页岩砖应发展大尺寸、低密度、高孔洞率的保温隔热砌块和空心砖 ;大强度、条窄孔、装饰性、多功能的承重清水墙多孔砖 ,高强度、高密度、低吸水率以及主要用于基础的页岩实心砖。逐步放弃低档次的传统的页岩混水墙砖。保护页岩资源 ,开发出高档次、高品位、高附加值的“三高”

In China, shale solid brick and perforated brick keep the main place of shale products. There exist great distance to developed countries on mechanical stress, appearance and heat preservation and heat insulation of shale products. The paper gives some proposals in developing shale brick of China.
