In a case of prolonged service life of old concrete structures by repair works, prediction technique of service life after repair is necessary to design durability of repaired structures. In this paper, carbonation speed about concrete repaired by several types of repair materials after carbonation were examined. Air permeability, pore size distribution, and carbonation speed of repair materials were also examined. And effects of these repair materials on carbonation speed of concrete were confirmed. From these results, some expression to predict prolonged service life that the carbonation speed of concrete repaired correlates closely with the air permeability and carbonation speed of repairing materials was proposed. And the flow of selecting repair materials for prolonged service life of old concrete structures, was proposed.
