采用挤压法生产的石棉水泥制品广泛用于建筑中。这种方法的优点是产量高、制品外表面质量好。但是由于水泥缺乏,所以只得用其它材料代替。无水泥挤压材料生产的发展方向是利用生产废料作胶凝材料,这样可以扩大原料基地和解决影响环保的有害物的利用问题。苏联研究和安装了一条年产14.4万米制品的生产线。利用电热磷渣和高炉矿渣试生产了 Asbestos cement products produced by extrusion are widely used in buildings. This method has the advantages of high yield and good surface quality of the product. However, because of the lack of cement, it has to be replaced with other materials. The development direction of the production of cementless extrusion materials is to use production wastes as cementitious materials, which can expand the raw material base and solve the problem of utilization of harmful substances that affect environmental protection. The Soviet Union studied and installed a production line with an annual output of 144,000 meters. Electrothermal phosphorus slag and blast furnace slag trial production
