PROBLEM TO BE SOLVED: To provide a construction method for infilling fast-curing lightweight infilled mortar, wherein 90% or more of air bubbles existing during injection are retained in the mortar even after placing by suppressing the dissipation of the air bubbles included in the fast-curing lightweight infilled mortar injected into a void area in water and the like. SOLUTION: Since the quantity of the fast-curing lightweight infilled mortar injected into the void area is set to be in the range of 2-20 m<SP>3</SP>/h, 90% or more of the air bubbles existing during the injection can be retained in the mortar even after the placing by suppressing the dissipation of the air bubbles included in the fast-curing lightweight infilled mortar injected into the void area existing in water. Consequently, a cellular mortar cured body, which exerts a high level of safety even in water, can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
