利用石灰与粉煤灰、炉渣或矿渣等含硅工业廢料生产硅酸盐制品,可作为很好的建筑材料。硅酸盐制品,按其硬化情况的不同,可分为3种: 1.自养的,即不經湿热处理,在室溫下自然硬化。2.蒸养的,即在100℃以下的饱和蒸汽中进行湿热处理。3.蒸压的,即在蒸压釜中用高于1个計示气压的饱和蒸汽湿热处理,常用的蒸汽压力为8个大气压,蒸汽的温度是174.5℃。按成型方法的不同,硅酸盐制品又可分为: 1.压制成型制品:成型压力自120公厅/厘
The use of lime-based fly ash, slag or slag and other silicon-containing industrial wastes to produce silicate products can be a good building material. Silicate products, according to their different hardening conditions, can be divided into three kinds: 1. Autotrophic, that is not wet heat treatment, at room temperature naturally hardened. 2. Steam-cured, ie wet heat treatment in saturated steam below 100°C. 3. Autoclave, i.e. saturated steam steam heat treatment in an autoclave with a pressure above 1 gauge. The usual steam pressure is 8 atmospheres and the steam temperature is 174.5°C. According to different molding methods, silicate products can be divided into: 1. Pressed products: molding pressure from 120 Hall / PCT
