PROBLEM TO BE SOLVED: To provide a lightweight grouting material capable of maintaining a flowability excellent in a long distance pressure-feeding ability by a pump, or the like, over a long time, also preventing the blocking in a mixer or a pipe in the case that the pressure-feeding of the grouting material must be stopped for a long time, and moreover suppressing the change of the unit volume mass of the lightweight grouting material by keeping air bubbles at a stable state, and a method for grouting by using such the lightweight grouting material.SOLUTION: This lightweight grouting material is constituted by 2 kinds of materials pressure-fed separately and mixed before the grouting is characterized in that the 2 kinds of materials are constituted by liquid A containing a latent water curable material and water, and liquid B containing a stimulating agent for causing the water curability for the latent water curable material and air bubbles, and the B liquid contains 10 to 30 wt.% alkali agent based on 100 pts.wt. water. |
