Description
Summary:Cover cracking from reinforcement corrosion is one of the major causes of deteriorations in reinforced concrete structure. If the cover cracking time can be predicted, it would be useful for maintenance planning and budget allocation. The objective of this paper was to find the influence of repair materials on concrete cover cracking time. In this study, the corrosion of concrete reinforcement was accelerated by electricity. Using three types of materials, it was found that the cover cracking time of repair mortar was the shortest followed by those of concrete and non-shrink cement grout respectively. In addition, specimens simulating repaired concrete were prepared. The cracking times of the repaired specimens were found to be about the same and were of the same order as those of repair materials only.
