PURPOSE:To prepare a grouting material having a good filling property by a method in which a specific grain size of converter slag or granulated slag, water-granulated slag, bentonite, and water are mixed toether in specific proportions in such a way as to give the mixture a specific unit volume. CONSTITUTION:A grouting material is prepared by mixing 38-65wt% converter slag or granulated slag of a grain size of 13mm. or less, 8-17wt% bentonite of a grain size of 1mm. or less, and 12-20wt% water in such a way as to give an unit volume of 2.0-2.8g/cm<3>. Or, as another example, 38-65wt% converter slag or granulated slag of a grain size of 5-13mm., 16-29wt% water-granulated slag of a grain size of 10mm. or less, 8-17wt% bentonite of a grain size of 1mm. or less, and 12-20wt% water are mixed together in such a way as to give an unit volume of 1.8-2.8g/cm<3>. |
