A Review on Preparation and Properties of Trigger-type Microcapsule Corrosion Inhibitors

Based on the theory of reinforcement corrosion of reinforced concrete, the preparation and triggering methods of microcapsules are summarized in combination with the material science of concrete. The trigger mechanisms and the triggering processes of different contact concrete microcapsules corrosion inhibitors are listed in detail. Some test systems, which are applicable to study basic properties and characterization of microcapsules, are introduced. The influences of microcapsules corrosion inhibitors on concrete properties are also reviewed. The disadvantages of the existed test methods are put forward. On the current basis, several key problems are proposed.
