| 摘 要： | 以梅山矿渣为研究载体,运用现代分析手段,研究了粒化高炉矿渣玻璃体的矿物组成和微观结构。研究结果表明:梅山矿渣玻璃体中潜在矿相为钙铝黄长石、少量的镁蔷薇辉石,不存在通常认为的β-C2S;玻璃体中的硅铝骨架并不是处于网状结构中,而是处于双四面体岛状结构中;核磁分析证实梅山矿渣中29Si处于Q1的环境中;该矿渣玻璃体中铝的配位数是4。

| Abstract: | The slag from Meishan Steel Company was used to research the mineral composition and microstructure of the vitreous body of granulated furnace slag. The results show that the potential mineral composition in the vitreous body of granulated furnace slag includes cacoclasite and a little merwinite, but differrent to the general opinion , the C2S doesn't exist in it. The silica- alumina framework in vitreous body exists not in reticular structure but in double tetrahedron island structure. The 29Si of Meishan slag exists in Q1 chemical condition by means of NMR and the coordination number of aluminum in the vitreous body is 4. |
