摘要:

研究了新型水化响应纳米材料作为混凝土抗侵蚀抑制剂对混凝土毛细疏水、离子传输、硫酸盐腐蚀以及钢筋阻锈性能的影响。水化响应纳米材料可以在海工低渗透性混凝土基础上进一步降低混凝土吸水率78%，降低氯离子扩散系数44%，硫酸盐耐蚀系数提升41%，同时降低钢筋宏电池累计腐蚀电量90%，实现钢筋混凝土结构整体耐蚀性能的大幅提升。

Abstract：

The effect of new kind of hydration response nanomaterials, as concrete erosion inhibitor, on capillary hydrophobicity, ions transport, sulfate corrosion resistance for concrete and corrosion resistance for the corresponding reinforced steel was investigated. For a low-permeability marine concrete, the addition of hydration response nanomaterials can further reduce its water absorption rate by 78%, chloride ion diffusion coefficient by 44% and sulfate corrosion resistance coefficient by 41%, whilst the electric charge cumulation due to corrosion of the reinforced steel by 90%, thus greatly improving the overall corrosion resistance of reinforced concrete structures.

Key words： concrete erosion inhibitor corrosion of steel capillary hydrophobic response of cement hydration nanomaterial
