Abstract

Mortar using for repairing on reinforced concrete structures. The substances such as carbon dioxide and chloride ion will be penetrated into the concrete or mortar. However, it is existing the interfacial transition zone between the aggregate interface and paste in the concrete. In this study, using a mortar obtained by removing the coarse aggregate from concrete, it was carried out a comparison of resistance of permeability between concrete and mortar. As a result, it decreases the permeability resistance by the water cement ratio is increased in ordinary Portland cement and blast furnace slag cement by carbonation resistant. The permeability resistance of concrete tends to decrease significantly compare to mortar by the interfacial transition zone. On the other hand, in case of the salt resistant, it is not clear the effect of it. Thus, it becomes formed pores like water reservoir to the lower surface aggregates by bleeding.
