Test methods of repair materials proper to water leakage crack of concrete structure

摘要

Despite multilateral studies on crack control in concrete structures in terms of structure, materials, and construction, there was no complete control of crack occurrence due to technological and materials-related limitations, which is directly related to water leakage, having adverse effects on long-term safety of structures.For continuous structure safety control, many countries are spending much money on water leakage repair but tail to get complete repair, which becomes one of very serious problems awaiting solution in construction technology throughout the world.
