Abstract: Polymer modified cement mortar has been used for the repair of concrete structures for over two decades. The polymers are basically expected to reduce the permeability of the repair mortar to water, carbon dioxide and external chemicals that can further deteriorate the life span of the concrete structures. However, the products on the market have not been compared thoroughly and simple methods are not available to the user for choosing an effective repair system. In the work reported herein, different types of commercially-available polymer modified cement repair materials with the same water to cement ratio were tested. The mechanical properties and permeability of these materials were evaluated to assess their performance. It was observed that though the strength of the cement mortar itself did not always improve due to the addition of the polymer, the pull off tests revealed good bond strengths between the repair material and base concrete.
