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.

智能材料的概念应用于混凝土。智能混凝土通过修复嵌入混凝土中的胶囊渗透的剂可以进行自我治疗。一旦发生裂缝，胶囊就可以作为检查器。仅对于一定的裂纹宽度，维修剂才能将其渗入裂缝中以填充空间。为了开发这种技术，进行了实验研究。结果表明，该技术可通过破裂的混凝土壁静止水，并且可以将破裂的混凝土恢复到一定水平。实验研究了几种类型的胶囊。还尝试使用类似的技术来恢复恶化的混凝土。
