An Estimation of the Long-Term Properties of Epoxy Used for Reinforcing Surface in Concrete

콘크리트 표면강화 에폭시의 장기특성 평가

Up to date, it is difficult to estimate the consistence of properties on the epoxy liner in service time because an estimation of the long term environment-deterioration with aging has not been processed. In the study, the estimation on epoxy liner is carried by the physical test 7 rounds. There are the elongation the and the crack bridging test in the part of physical tests. An elongation test is carried out with epoxy membrane and a crack bridging test is carried out with specimen painted epoxy on concrete. The subjects of test and estimation are a containment quality system and a fibre-glass reinforced system. The materials of these systems are a Robber added Epoxy, a Silica added Epoxy, and a Fiber reinforced Epoxy. Ensuring the test data, properties of epoxy liner was estimated and the change of properties was predicted on epoxy liners.
