<p><P>PROBLEM TO BE SOLVED: To provide a grout capable of eliminating washing with water on completing a work although it is a two liquid type, and a method for grouting the same. <P>SOLUTION: This grout consisting of slag, lime and water glass as essential components is constituted by setting a self-curable mixed liquid consisting of the slag and water glass containing 5.3 to 0.50 wt.% water glass of≥JIS 3 grade material by molar ratio based on Na<SB>2</SB>O as liquid A and a non-self-curable suspension consisting of the lime as liquid B, and curing the slag in the liquid A by mixing the liquid A with liquid B. Since the slag is not cured for around 10 days, it is not necessary to wash a dispense line, etc., to a flow-unifying part of mixing the liquid A with liquid B with water everyday even in a construction of which execution has a time restriction or in a back filling work of a sealed tunnel having a long compression sending distance. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
