The present invention relates a grout composition, which comprises 10-60 weight% of inorganic binding agent, 10-60 weight% of fine aggregate, 0.01-20 weight% of polymeric admixture and 1-30 weight% of water, wherein the polymeric admixture comprises 75-99 weight% of styrene-butadiene resin, 0.1-10 weight% of butylene-methacrylate resin, 0.1-10 weight% of maleic amide, 0.1-10 weight% of acryl nitrile and 0.01-5 weight% of phenol resin, and a grouting method using the same. According to the grout composition of the present invention, filling in the cracks on the ground is possible as the strength, the durability and the fluidity are excellent; the service period is increased, the maintenance cost is reduced and the constructability is enhanced as the field applicability, the workability, the durability, the adherence and the water proof property are excellent; the construction is facilitated as the fluidity is excellent; the construction period and the construction cost are reduced due to the rapid hardening; the stability of the reinforced ground is enhanced and the drying shrinkage occurring in hardening and drying is able to be compensated by maximizing the displacement restraint on an excavation side and the pullout resistance. |
