The purpose of this study. To study comparison, repair cracks of reinforced concrete columns between epoxy resins with cement grout are not contracted by testing reinforced concrete columns size 0.20 x 0.20 x 0.45 m. Consisted of 30 samples, which will break the test into three. The group is pressing the compression test maximum axial 10 example to test a hiatus of 20 samples and then repaired with epoxy resin and cement grout are not shrinking species from 10 samples and then bring back a lot. The maximum axial compression test.
