Lamellar inorganic fillers have been used to improve the performance of polymer composites. In this paper, five kinds of lamellar inorganic fillers, including montmorillonite (MMT), mica, talc, glass flake (GF) and lamellar double hydroxide (LDH), were selected to modify epoxy emulsion cement mortar (EECM). The research evaluated the effects of the structure characteristics of lamellar fillers on the mechanical properties, water absorption and chloride ion permeability resistance of EECM, with comparison to granular ground calcium carbonate (GCC). Results indicated that lamellar fillers had no obvious superiority than GCC in the mechanical strength of EECM, even MMT caused the decline of the mechanical strength. However, lamellar fillers had improved the chloride ion permeability resistance of EECM compared with GCC, and they had the similar effect on reducing of water absorption except MMT. Although the low aspect ratio (AR) of the lamellar fillers benefited the increase of the strength and water resistance of EECM, the lamellar fillers with higher AR could improve the chloride ion permeability resistance of EECM more efficiently.

层状无机填料对环氧乳液水泥砂浆性能的影响

层状无机填料已被用于改善聚合物复合材料的性能。本文选取蒙脱石（MMT）、云母、滑石、玻璃鳞片（GF）和层状双氢氧化物（LDH）5种层状无机填料对环氧乳液水泥砂浆（EECM）进行改性。该研究评估了层状填料的结构特征对 EECM 的机械性能、吸水率和氯离子渗透阻力的影响，并与粒状重质碳酸钙 (GCC) 进行了比较。结果表明，层状填料在EECM的机械强度上没有明显优于GCC，即使是MMT也会引起机械强度的下降。然而，与 GCC 相比，层状填料提高了 EECM 的抗氯离子渗透性，除MMT外，它们在降低吸水率方面具有相似的作用。虽然层状填料的低纵横比（AR）有利于提高EECM的强度和耐水性，但具有较高AR值的层状填料可以更有效地提高EECM的抗氯离子渗透性。
