| Abstract |
In these days, Various constructive methods of anticorrosive coating to protect the concrete constructions in the vitriolic environment such as drainages are considered. In the research, an applicative lining method of construction applied existing glass fiber cross which has the most positive achievement is compared with a method applied new glass fiber cross to verify the effect of newly invented glass fiber cross and how it controls occurring pinholes.
The following conclusions were obtained from the present study.
(1) When existing glass fiber cross which is thick and has loose fiber intervals is used to secure thickness of layer, the occurring possibility of pinholes is increased by mixed air during the construction and viscosity of paints.
2) Adhesive strength highly exceeds 1.5 MPa
(3) Generally, observed pinholes and mass change are increased together. When exiting glass fiber cross is used, viscosity of paint is increased and controlling effect of occurring pinholes is also increased. However, controlling effect of evaporation is not observed. When new glass fiber cross is used, evaporation of the moisture is not occurred after 4 weeks.
(4) If viscosity of paints is high, controlling effect of pinhole is also getting higher. |
