摘要


混凝土的裂缝和空隙会导致耐久性的损失。当裂缝到达钢筋混凝土结构表面时，可以用各种方法进行修补，
但对于荷载重复作用引起的潜在缺陷或微裂缝，由于无法通过表面状态进行检测，目前还没有有效的修补方法。在
本研究中，我们使用用于修复的涂层材料检测了掺有外加剂的混凝土的自修复性能的存在与否，该涂层材料已经使
用了很长时间。由此，通过试验确定了掺外加剂混凝土的基本特性，证实了其自修复性能。考虑到受损混凝土强度
的恢复，掺有表面涂层剂的混凝土比掺有非混合混凝土的混凝土显示出更大的恢复效果。随着受损材料的老化，这
种影响更大。这表明，即使将修复涂层材料作为掺合剂混合，也保持了晶体增殖效果，并且证实了混合有掺合剂的
混凝土具有自修复性能。
