Abstract
The goal of this research project is to expand the previous work on a timed adhesive release system for the repair of cracks in concrete. The performance criteria for the adhesive are that it must have a long shell life, be resistant to extreme temperatures, have a high viscosity so it can flow easily into cracks in concrete and it must be strong enough to repair the cracks. The method of encapsulating the adhesive must not degrade over time and it must not be costly. A three-part methylmethacrylate adhesive system was chosen. The adhesive was released from hollow glass tubes coated with a brittle breakable sealer. The experimental results showed the release of the three-part methylmethacrylate adhesive into the matrix created a bond that restored the lost strength due to the cracking and increased flexibility.Keywords
