Title:
GROUND CONSOLIDATION METHOD
Document Type and Number:
Japanese Patent JP2014202646
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground consolidation method by which decontamination work can be quickly performed without re-diffusing radioactive substances.SOLUTION: There is provided a ground consolidation method for consolidating the ground by feeding 100 pts.mass of solidification material containing blast furnace slag and calcium aluminates, adding 70-300 pts.mass of water in the middle thereof to form solidification material slurry, and spraying the solidification material slurry onto the ground. It is preferable that a used amount of the calcium aluminates is 10-100 pts.mass with respect to 100 pts.mass of the blast furnace slag. The solidification material may contain fiber. It is preferable that the length of the fiber is 3-10 mm.
