Abstract

This study sought to ascertain the efficacy of epoxy repair materials in enhancing structural integrity when applied to concrete specimens that had been purposefully cracked. Flexural strength and ultrasonic pulse velocity tests were utilised to assess the success of repair both quantitatively and qualitatively. Researchers are better able to investigate material efficiency, waste reduction, and sustainability in repair processes when epoxy consumption is quantified. In the current investigation, the amount of repair material required was evaluated experimentally. The current study evaluated the impact of epoxy repair on beam specimens having dimensions 10cmX10cmX50cm with varying crack widths of 0.5 mm, 1 mm, 1.2 mm, and 1.4 mm at a constant depth of 3 cm. It is possible to evaluate the quality and integrity of the repair material and guarantee the structural soundness of the concrete by measuring the pulse velocity through the repaired area. To guarantee consistency and obtain an average value, several pulse velocity measurements were made at various points. Specimens that were cracked, uncracked, and repaired were tested in order to compare the results. The quality of the specimen improved following repair, according to a comparison of the pulse velocity values of the cracked and repaired specimens. Flexural strength test results show that the repaired specimen’s flexural strength is greater than that of the cracked specimen but lower than that of the uncracked specimen. Gaining insight into the differences in flexural performance between repaired and uncracked specimens can help improve repair techniques and guarantee the long-term durability of concrete structures.
