Recently, the concern with acrylic resin as a new repair material has been growing. The acrylic resin is characterized by high quality, low viscosity, highly elongation percentage and so on. Several studies have been made on the crack repair by using acrylic resin, but little is known about the effect of acrylic resin as a crack repair material for concrete.<br>The purpose of this study is to examine the applicability of acrylic resin for using as a crack repair material for the concrete structures. The fundamental mechanical properties of acrylic resin by using super lightweight powder were examined. And the repair effects of acrylic resin as crack repair material were examined by the flexural loading test of the concrete member repaired by crack injection technique. As a result, acrylic resin could adjust the viscosity by using super lightweight powder, and the elongation percentage of acrylic resin was superior to epoxy resin. The crack repair effects of acrylic resin were equivalent to the epoxy resin under drying condition of the crack surface of concrete member.
