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 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。
Analyzing the factors of concrete workability , mechanics quality , durability , cost , the key of mamufacturing lc - hpc are compatible of chemical admixture , stability of volume durability are pointed out , at the same time the principle and the technique route of lc - hpc is put forward 通过对影响混凝土工作性、力学性能、耐久性、生产成本的因素分析，指出混凝土化学外加剂的兼容性、体积稳定性、耐侵蚀能力是lc - hpc配制的关键，提出了lc - hpc配制原则和技术路线。
