The present invention contains water and cement at a water cement ratio (W/C) of 0.90 to 1.20, and liquid A containing 60 to 120 parts by weight of main material based on 100 parts by weight of the cement, and 0.90 to Water-cement ratio (water cement ratio (W/C) of 1.20) containing water and cement, and based on 100 parts by weight of the cement, the B solution containing 60 to 120 parts by weight of an activator is 1: 0.8 to 1.5 volume ratio Mixed with; The main material is based on 100 parts by weight of calcium fluorite smelting by-product, 50 to 70 parts by weight of circulating fluidized bed boiler fly ash, 10 to 30 parts by weight of aluminum silicate, 1 to 10 parts by weight of dimethylsiloxane fluid, 1 to 10 parts by weight of lupeol, the following 1 to 10 parts by weight of a tyrane compound represented by Formula 1, 0.1 to 5 parts by weight of a superplasticizer, and 0.1 to 5 parts by weight of a retarder; [Formula 1] (m represents the integer of 0-4, n represents the integer of 0-2.) The activator is based on 100 parts by weight of amorphous calcium aluminate (C12A7), 10 to 30 parts by weight of calcium sulfo aluminate, 10 to 30 parts by weight of anhydrite, 1 to 10 parts by weight of a thioepoxy compound, 0.1 to allyl isothiocyanate Including 5 parts by weight, 0.1 to 5 parts by weight of a curing accelerator, and 0.1 to 5 parts by weight of a superplasticizer; It relates to a two-component grouting composition for reinforcing tunnel steel pipe grouting capable of rapid hardening and early high strength expression, and a tunnel steel pipe grouting reinforcement method using the same. |
