Abstract
This research was to evaluate the shrinkage and durability performance of latex modified repair mortar and to improve the service life of the agricultural concrete structures. The shrinkage characteristics of the repair material creats the delamination of repair materials and existing concrete. It is possible to happen the problem to reduce a service life. Also, the reduction of durability performance of the repair materials induce the destruction of the repaired concrete structures at the early stage. Therefore, this research are evaluated the plastic and drying shrinkage, thermal expansion coefficient for shrinkage properties, and for durability performance, the permeability, repeated freezing and thawing, and resistance of chemical solution test were performed. Test results showed that the latex modified repair mortar indicated the shrinkage amount which the delamination does not happen, and the latex modified repair mortar appeared excellent long-term durability performance which can increase the service life.
