PROBLEM TO BE SOLVED: To efficiently and costlessly form a secure solidified body without intrusion of a solidifying material used for improvement for a ground into cracks of the ground at a specified position, on the basis of the design, in a compaction grouting method newly developed recently. SOLUTION: The range of size distribution of aggregate for a solidifying material used for the compaction grouting method is within 50% in the gravel fraction, 40-70% in the sand fraction, and within 30% in the fine fraction, as a standard base. The material has a gently opened particle size cumulative curve in these ranges. Adding water is within a low slump range of 0-10 cm. Further, the material is used so that an execution based on a design can be accurately carried out while using a recyclable waste materials such as ready- mixed concrete waste, concrete waste, coalash, bottom ash, etc.
