NON-SHRINK CHEMICAL GROUT MATERIAL COMPOSITION AND GROUTING METHODS USING THEREOF

摘要

The present invention relates to a non-shrink grout material composition and a grouting method using the same, wherein the non-shrink grout material composition comprises: 20 to 60 parts by weight of water; 0.01 to 5 parts by weight of a shrinkage reducing agent; 10 to 30 parts by weight of calcium sulfo-aluminate; 10 to 50 parts by weight of fly ash; 0.1 to 10 parts by weight of a viscosity agent; and 1 to 5 parts by weight of a high performance water reducing agent, with respect to 100 parts by weight of cement. According to the present invention, the grout material composition enables to prevent an occurrence of the number of bleeding by suppressing a material separation, and to improve workability by maintaining high liquidity as well as securing endurance time of the entire structure by securing a filling performance during grouting.
