Towards durable concrete that repairs cracks autonomously

Kim Van Tittelboom UGent, Nele De Belie UGent, Frank Lehmann and Christian Grosse (2010) Proceedings pro074 : international RILEM conference on use of superabsorbent polymers and other new additives in concrete. p.285-292
abstract
Concrete is frequently used as construction material because of its excellent mechanical properties, low cost and freedom of design. However, one weakness of concrete is its susceptibility to cracking. Aggressive liquids and gasses may enter these cracks and cause concrete deterioration, so the durability of the structure is impaired. Therefore, it is important that cracks are repaired as soon as possible after they arise. In this research, it was attempted to use crack formation as a trigger to cause immediate crack repair. Concrete beams, provided with encapsulated healing agent, were tested on their autonomous crack healing efficiency. A comparison was made with manually healed cracks. It was seen that in the case of manual crack healing up to 60 % of strength recovery was obtained while for the specimens with self-healing properties a maximum of 97 % of regain in strength was noticed. This means that it is possible to induce crack repair by crack appearance. Use of this technique may lead to concrete structures with a longer life span.
