Fundamental experiment on repair effect of acryl resin to damaged concrete

Abstract

This paper proposes experimental approaches on the repair effect of an acryl resin to damaged concrete. Mechanically different three types of the repair specimens are used. First one is the cohesion performance test specimen which has a horizontal split plane repaired by acryl resin. Its bond performance is evaluated by direct tensile test. Second one is the shear stress performance test specimens which have a diagonal split plane repaired by acryl resin. Its shear resistance is evaluated by ordinal compression test. Third one is a micro-crack damaged specimen of which cracks are repaired by infiltrated acryl resin. Its repaired effect is evaluated by using ordinal compression test.
