Document Type and Number:
Japanese Patent JP2007106961
Kind Code:
A
Abstract:
To obtain a grouting material that secures penetration to the ground and increases ground strength.
A grouting material comprising blast furnace slag fine powder or coal ash is mixed with sodium sulfate or sodium sulfite which are a hardness improving agent. The amount of sodium sulfate mixed is 1-20 wt.% in the composition of the grouting material. Blast furnace slag fine powder and an alkali salt are stirred and mixed with kneading water by a laboratory mixer to prepare a grouting material, which is injected into the ground. Consequently, the grouting material secures penetration to the ground and increases ground strength.
