Abstract:
Injection methods for repairing concrete to maintain the integrity of structural members were studied. As a general rule, the lower is the viscosity of epoxy, the longer the setting time and the deeper the grout goes. Further, the deeper the placing, the better the result will be. In the actual case, splitting tension test of core cylinders from repaired sections show that the repair method that adopts a specially designed injector will do better work than that using a conventional one.
