Abstract: The purpose of this study is to compare normal and epoxy-repaired concretes. The test results show that the average compressive strengths of normal concrete, epoxy-repaired concrete Type 1, and epoxy-repaired concrete Type 2 at 21 and 28 days are 21.99 N/mm2 and 25.03 N/mm2, 20.58 N/mm2 and 25.36 N/mm2, and 22.44 N/mm2 and 25.53 N/mm2, respectively. There were 13.79%, 23.19%, and 13.79% strength improvement between the 21- and 28-day period in normal concrete, epoxy-repaired concrete Type 1, and epoxy-repaired concrete Type 2, respectively. The study concludes that epoxy can effectively restore and even improve the structural integrity of cracked concrete.
