耐碱砖（JC/T496-96）
Alkali resistant bricks 
本产品采用半硅质原料，以化学结合不烧工艺生产而成，它具有强度高、隔热效果好、抗碱侵蚀能力强的特性，主要用于大型水泥回转窑筒入料区段、预热器、三次风管和分解带等碱侵蚀严重的部位。
These produels are produced by the techniques same with chemical bonded non-sintered bricks with semi-silica raw materials, They have high strength,good heat insulating and alkali resistant properties, They are mainly applied to the zones of large-sized cement rotary kilns which are croded badly by alkali, for example, the input zone, preheater, three-windtunnel, and decomposing zone.
