PROBLEM TO BE SOLVED: To provide a light weight cement-based grout material composition and a light weight cement-based grout material with surrounding environment taken into consideration, especially a light weight cement-based grout material composition and a light weight cement-based grout material generating little dust when mixed with water.SOLUTION: In one embodiment, the light weight grout material composition is provided that contains cement, a light weight aggregate having unit volume mass of less than 0.3 kg/L and oxyalkylene alcohols of 0.3 to 5 mass%. In another embodiment, the light weight grout material composition is provided which is identical to the light weight grout material composition in the above one embodiment except that an average addition molar number (n) of an oxyalkylene group of the organic compound is 1 to 5, the content of the light weight aggregate is 3 to 20 pts.mass based on 100 pts.mass of the cement and the light weight grout material composition contains one or, two or more kind selected from an expansive admixture, a thickener and a foaming agent.SELECTED DRAWING: None |
