Developement of Intelligent Concrete with Self-Curing Potential

将智能材料的概念应用到混凝土中。智能混凝土具有通过从混凝土中嵌入的胶囊渗透的修复剂进行自我修复的潜力。一旦出现裂缝，这个胶囊就会起到审查的作用。只有在一定的裂缝宽度下，修补剂才会渗透到裂缝中填补空隙。为了发展这项技术，进行了实验研究。结果表明，该技术可有效地截留裂缝混凝土墙体中的水分，并可使裂缝混凝土恢复到一定程度。对几种类型的胶囊进行了实验研究。并尝试了采用类似技术对劣化混凝土进行回收的可行性。

Concept of intelligent materials was applied to concrete. Intelligent concrete has a potential to self-cure by repairing agent percolated from capsules embedded in the concrete. Once a crack occurs, the capsule works as a censor. Only for a certain crack width, the repairing agent percolates into the crack to fill up the space. To develop this technique, experimental studies were carried out. The results showed that this technique is available to still water through cracked concrete wall, and that cracked concrete can be recovered up to a certain level. Several types of capsules were experimentally investigated. Availabilty of recovery of deteriorated concrete was also tried with the similar techniques.
