Abstract

Concrete is so sensitive to tensile stress that cracking is common in reinforcedconcrete structures, such as buildings and bridges. Cracking in concrete affects theperformance and durability of structures. Repairing cracked concrete is costly andremains ineffi cient in many cases. To ensure good performance, initial cracksshould be controlled and, if possible, repaired at their earliest stage. This researchstudies smart concrete, using a superabsorbent polymer (SAP) to seal and healcracks autogenously. An extensive experimental program including pull-out testson different concrete mixes was carried out to study the healing of concrete atrebar-concrete interfaces. Results show the promise of signifi cant strengthrecovery using SAP to partially seal and heal cracks.
