PROBLEM TO BE SOLVED: To impart excellent preservability as compared with a premix type, to obtain a uniform mixture, to simply perform execution and to reduce transport cost. SOLUTION: In the production of a grout material, cement and an intimate mixture are separately charged in bags as one units and the intimate mixture contains silica sand and at least one kind of a component selected from fly ash, calcium carbonate and cement and also contains at least one kind of a component selected from a re-emulsifying powder resin, a water reducing agent, a deforming agent, an expanding agent, shrinkage reducing agent, a thickener, a fiber and a slag fine powder and one or more unit of cement is taken out of the bag to be mixed with water and, thereafter, the intimate mixture is added and mixed and the bag may be composed of a water-soluble substance. This intimate mixture is either one of silica sand, calcium carbonate or cement (1), at least one kid of the re-emulsifying powder resin and the water reducing agent (2), at least one kind of silica sand, calcium carbonate, cement or the slag fine powder (3) or at least one kind of calcium carbonate, cement or a slag fine powder (3). |
