摘要

为获得环氧树脂含量、固化时间等外界因素对地聚合物抗压强度和耐海水腐蚀性能的影响机理，采用NaOH和Na2SiO3作为活化剂;通过实验研究了环氧树脂浓度对偏高岭土聚合物耐腐蚀性能的影响。采用x射线衍射、扫描电镜-能谱和傅里叶变换红外光谱分析了环氧树脂浓度对聚合过程和地聚合物性能的影响机理。结果表明，环氧树脂减缓了聚合反应。环氧树脂的存在有利于结构致密化。与无腐蚀试样相比，掺入30%的试样经过1d、3d养护和56d浸泡后的平均抗压强度分别提高了4.77MPa和4.24MPa。

Epoxy Resin’s Influence in Metakaolin-Based Geopolymer’s Antiseawater Corrosion Performance

To obtain the influence mechanism of epoxy resin content, curing time, and other external factors on the compressive strength and seawater corrosion resistance of geopolymer, the NaOH and Na2SiO3 were used as activators; the effect of epoxy resin concentration on the corrosion resistance of metakaolin-based geopolymer was investigated by experiments. The mechanism of epoxy resin concentration affecting the polymerization process and the properties of geopolymer was analyzed by X-ray diffraction, scanning electron microscopy-energy spectrum, and Fourier transform infrared spectroscopy. It was shown that the epoxy resin slowed down the polymerization. The presence of epoxy resin had a beneficial effect on compact structure. Furthermore, compared with the noncorrosive specimen, mixed with 30% specimen’s average compressive strength increased by 4.77MPa and 4.24MPa after curing for 1d and 3d and soaking for 56d.
