AN EFFECTIVE AND ETERNAL MAINTENANCE METHOD FOR CONCRETE TUNNEL STRUCTURES

This paper presents the results of a study to confirm that a cement crystal increasing material is effective to make concrete itself impermeable and to suppress every kind of damage and deterioration, by increasing cement crystals in pores and voids of concrete body. It is a quite different method from ordinary ones by coating and injecting resinous materials which have properties that are different from concrete to the surfaces and into the cracks as physical barrier. The effects of application with the material was verified by permeability test and SEM (Scanning Electron Microscope) survey with concrete specimens and cylindrical test pieces from the concrete linings of some tunnels in service by applying this material.
