海洋环境下掺新型抗腐蚀外加剂水泥基砂浆耐久性能的试验研究

Experiment Research on Durability of Cement Mortar with a New Anti-corrosion Admixture in Marine Environment

在抗腐蚀外加剂与混凝土外加剂适应性试验的基础上,用人工配制的盐水来模拟海洋环境,通过强度试验、微观孔结构和氯离子渗透试验,证明了所配制的新型抗腐蚀外加剂能使水泥砂浆致密性增强,可保持砂浆强度的稳定性,并具有良好的抗氯离子渗透性能。

Based on the compatibility tests of anti-corrosion agents and chemical admixtures of concrete, the marine environment was simulated by a man-made solution. Through the tests of strength, micro-pore structure and chloride permeability, it is proved that the new anti-corrosion admixture can enhance the density of cement-based mortar and maintain the stability of mortar strength, and the cement-based mortar could have a good chloride-penetration resistance.
