Abstract

Self-healing concretes have embedded adhesives which are released from hollow fibers inside the concrete when and where cracking of the matrix and the fibers occurs. It was found that the adhesive improves the strength of the cracked portions of the concrete and increases its ability to deflect under load. Structural materials subjected to dynamic events such as earthquakes and impacts can have improved response by the noise of adhesive type which can impart improved damping, lateral stiffness, or deflection. Testing also assessed the improvement of the bond strength in structures. In laboratory tests the internal adhesive repair system improved the bond between the reinforcing steel and the concrete to prevent pullout failure or debonding at the interface.
