Document Type and Number:
WIPO Patent Application WO/2012/108360
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing; a filling material exerting excellent waterproofing effects and exhibiting excellent durability and high permeability; and a filling method. A filling material formed by combining: material (A) containing water, a dispersant, and a zirconia silica fume having an average particle size of 1.0 μm or less; and material (B) containing water, a dispersant, and a calcium compound having an average particle size of 1.0 μm or less. The calcium compound is formed from a calcium hydroxide, and the amount of dispersant used in terms of solid matter is 0.1 to 30 parts by mass or 1 to 30 parts by mass in relation to 100 parts by mass of the zirconia silica fume or the calcium compound. A method for producing said filling material, wherein a wet dispersing process or a wet grinding/dispersing process is performed by means of a grinder employing high-pressure water. A filling method for combining material (A) and material (B) by means of a one-shot method, a 1.5-shot method, or a two-shot method and for filling the ground with the combined materials.
