摘要： PROBLEM TO BE SOLVED: To provide a grouting material in which a cementitious material and a dispersant are kneaded and mixed with seawater, wherein the decrease of fluidity can be controlled, and the injection can be performed over an sufficient breadth.SOLUTION: The grouting material is made by mixing and kneading a cementitious material and a dispersant, and kneading and mixing them with water. Seawater is used as the kneading and mixing water, and a nitrite is used to improve fluidity as a special admixture. Calcium nitrite is suitably used as the nitrite. As for a dispersant, a naphthalenesulfonic acid-based surfactant is suitably used.
