摘要： 以偏高岭土、粉煤灰为原料，在碱性激活剂作用下，采用适当工艺处理，在50～100 ℃的较低温度下，通过化学聚合反应制备出了高性能的人造矿物聚合物。试验研究表明：当最佳氧化物摩尔比为n(Na₂O)/n(SiO₂)=0.30，n(SiO₂)/n(Al₂ O₃)=3.7，n(H₂O)/n(Na₂O)=17时，所制备的人造矿物聚合物1 d抗压强度可达47.19 MPa，28 d抗压强度可达53.81 MPa；采用X衍射、电镜扫描和红外等方法对人造矿物聚合作用的微观机理进行了探讨。

Abstract: With metakaolin and fly ash as raw materials，the high performance artificial geo-polymer is prepared which results from the chemical polymerization reaction with alkaline activator at low temperature of between 50℃ and 100℃. The test results showed that when the mole ratio Na₂O/SiO₂ is 0.30，the mole ratio SiO₂/Al₂O₃ is 3.7，and the mole ratio H₂O/Na₂O is 17 of the optimal oxides，the 1-day compressive strength of the geo-polymer can reach 47.19 MPa，and the 28-day compressive strength can reach 53.81 MPa. The microcosmic mechanisms of artificial geo-polymerization were assessed through a variety of techniques such as X-ray diffraction (XRD)，scanning Electron Microscopy (SEM) and Infrared (IR) spectroscopy.
