The present invention relates to a composition for an eco-friendly fast-hardening grouting, and more particularly, to a composition for a steel pipe multi-stage eco-friendly fast-hardening grouting, which shortens the curing time of the injection material and has an early initial strength expression and has eco-friendliness. The composition for eco-friendly fast-hardening grouting of the present invention is in a sealant composition for multi-stage steel pipe grouting, The seal material is 5-18 parts by weight of calcium sulfo aluminate, 8-20 parts by weight of gypsum, 5-12 parts by weight of slaked lime, 10-20 parts by weight of fly ash, 32-48 parts by weight of kaolinite, 0.1-2 parts by weight of high-activating agent, Characterized in that it contains 0.1 to 1 part by weight of the curing accelerator. |
