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.

将智能材料的概念应用于混凝土。智能混凝土是一种具有自修复能力的混凝土材料。一旦出现裂缝，胶囊就像一个检查器。修补剂只有在一定的裂缝宽度时才能进入裂缝中进行填充。为了开发这种技术，进行了实验研究。试验结果表明，该技术可以有效地抑制裂缝混凝土墙体的渗水，并使裂缝混凝土得到一定程度的恢复。几种类型的胶囊进行了实验研究。并对劣化混凝土的修复进行了试验研究。
