In this study, for the purpose of efficient use of paper sludge which was industrial waste generated from paper manufacturing company, we verified the characteristic and utility of air mortar that used paper sludge as admixture. After the filling material had been set as a usage, basic physical properties, durability, and the segregation resistance were confirmed by the indoor examination and the practicality was examined on the construction site. As a result of the indoor examination, it was confirmed that a basic performance as the filling material was satisfied enough, and deterioration due to the repetitions of dry-wet and freeze-thaw was not seen. In addition, the great improvement of the segregation resistance was confirmed compared with usual air mortar. Similar characteristic was demonstrated in the construction site, and the improvement of construction was confirmed. Therefore, the paper sludge could be considered to be useful as the mixture material for the air mortar.
