摘要
以沸石为主要造岩矿物的岩石称为天然沸石岩（或称为天然沸石）。沸石是具有架状结构含水铝硅酸盐矿物，含有碱及碱土金属离子。在建筑材料中最常用的有斜发沸石和丝光沸石。掺天然沸石粉的水泥（或称沸石水泥）具有许多特殊的性能：提高抗渗性、预防碱———骨料反应膨胀、抗冻性好等。天然沸石在中国贮量大，分布面广。
The rock containing zeolite as its main rock-forming mineral is called natural zeolite rock(natural zeolite) Zeolite is a water-bearing aluminium silicate mineral with framework structure It contains K,Na +,Ca ++ ,Mg ++ ,ect The Clinoptiloite and Mordenite of the most commonly used zeolites in building materials Cement blended natural zeolite powder(also defined as zeolite cement)has many special properties of increasing permeability resistance,preventing expension due to alkali-aggregate reaction, freezing damage resistance,ect The natural zeolite is widespread and abundant in China,The cement factories near the natural zeolite producing area all use it as an admixture to product aeolite cement.
