<p>PURPOSE:To provide a grouting liquid for producing a high-strength solidified material, having gel time easily controllable over a wide range, especially to a relatively long gel time, exhibiting excellent impregnation property for a suspension-type grout and, accordingly, especially suitable for injecting into a water-permeable ground such as sandy soil. CONSTITUTION:This grouting liquid is composed of a suspension-type grout containing a mixture of fine slag particles and fine cement particles. The average particle diameter of the stag and the cement is <=10mum each and the specific surface area is >=5,000 cm<2>/g each. The mixing ratio of the cement is <=50%. The suspension-type grout is further incorporated with a water glass and/or an alkaline material.</p> |
