Abstract
Reduction in the useful service life of reinforced-concrete structures, mainly due to corrosion of reinforcing steel, is a major problem faced by the construction industry worldwide. Repair and rehabilitation of the deteriorated structures is essential not only to use them for their intended service life but also to assure the safety and serviceability of the associated components. While several repair materials, both cement- and polymer-based are available for repair and rehabilitation of the deteriorated concrete structures, their performance under hot-weather conditions has not been thoroughly investigated. This study was conducted to evaluate the performance of cement- and polymer-based repair materials under hot-weather conditions. Strength and durability characteristics of these repair materials were evaluated under elevated temperature and low humidity. It was noted that the combined effect of high temperature and low humidity conditions, though not harmful to the strength characteristics of the repair materials, severely accelerates their shrinkage. Based on the data developed in this study, performance criteria for evaluation of repair materials for hot and arid conditions are suggested.
