摘　　要：水泥基渗透结晶型防水剂具有良好的防水及二次抗渗性能。利用扫描电子显微镜、XRD对掺有水泥基渗透结晶型防水剂的水泥净浆样品进行观察。结果表明,掺防水剂的水泥净浆中水化凝胶晶体更多,水泥水化程度加大,混凝土密实度提高,改善了混凝土的抗渗透性能。Cementitious capillary crystalline waterproofing agents have excellent waterproofing properties and second infiltration resistance. Research has been done on cement paste sample with cementitious capillary crystalline waterproofing agents by SEM and XRD. The results indicate that the cement paste with waterproofing agents has more hydration binding crystals and further cement hydration. The density and infiltration resistance of the concrete are improved.
