Title:
固結性材料
Document Type and Number:
Japanese Patent JP6984192
Kind Code:
B2
Abstract:
To provide a solidifying material, especially at the time of construction using sand compaction pile (SCP) construction method used for liquefaction countermeasure, capable of securing a time lag (about 4 weeks) until the curing is started, while preventing expansion of the slag itself, i.e., capable of preventing breakage of a preceding casting pile due to the influence of horizontal soil pressure by advancing pile casting in the meantime.SOLUTION: The present invention is a solidifying material containing molten iron pretreated slag and granulated blast furnace slag, the solidifying material contains the granulated blast furnace slag in a ratio of 2.5 to 10.0 parts by weight based on 100 parts by weight of the molten iron pretreated slag, and also provided is a method of controlling the curing start timing using such solidifying material.SELECTED DRAWING: Figure 2
