摘要
采用高炉矿渣微粉制备了无机聚合物胶凝材料,并从其化学组成、微观物相结构、细观结构的表征分析入手,结合胶砂试样力学性能、耐腐蚀性能和耐高温性能的测试分析,阐明该材料体系耐腐蚀和耐高温性能方面的特性。研究结果表明,无机聚合物为具有快凝高强特性的铝硅酸盐类化合物,主要是以-Si-O-Si-键或Si-O-Al-O键构成的具有链状、层状和三维架状结构特征的非晶态结构,其细观结构均匀致密,孔洞多为封闭孔洞。致密的结构和稳定的-Si-O-Si-键或Si-O-Al-O键赋予无机聚合物优异的耐酸腐蚀性能和耐高温性能。
The inorganic polymer, using ground granulated blast furnace slag （GGBS） as raw mateiral, were prepared by adding a composite activator. The chemical composition and microstructure of the inorganic polymer were examined. The characteristics of corrosion resistance and high temperature resistance were investigated comparing with Portland cement samples. The mechanism was also discussed. The results show that inorganic polymer has amorphous-Si-O-Si- and Si-O-AI-O structure, and its microstructure appears denser than Portland cement. The corrosion resistant and high temperature resistant properties of inorganic polymer are much better than those of Portlant cement due to compactive microstructure and stable aluminum silicate compound of the inorganic polymer.
