The underwater grout material and the underwater grout construction method null high-molecular substance which

摘要

PURPOSE: To obtain an underwater grouting material low in viscosity just prior to be placed, seldom causing pipe cloggings, etc., capable of realizing force feed effect on an adequate placing height, developing material segregation resistance, and gellable within several tens minutes, and to provide an underwater grouting work using this material. ;CONSTITUTION: This underwater grouting material comprises cement, a polymer and an acidic solution. A second version of the grouting material comprises the above grouting material and a calcium aluminate compound and a setting regulator. A third version of the grouting material is composed of A-liquor comprising a polymer and an acidic solution and B-liquor comprising cement and water. The underwater grouting work uses any one of these grouting materials.;COPYRIGHT: (C)1996,JPO
