摘要

The present invention is an eco-friendly grout composition for filling old closed pipes of a one-component type for filling old closed pipes buried in the ground by mixing with water, based on 100 parts by weight of blast furnace slag, 10 to 50 parts by weight of fly ash; 10 to 50 parts by weight of polysilicon sludge; 1 to 20 parts by weight of at least one selected from the group consisting of desulfurized gypsum, quicklime, slaked lime, and mixtures thereof; 0.5 to 10 parts by weight of bentonite, 0.5 to 10 parts by weight of zeolite, and 0.5 to 10 parts by weight of a performance improving agent; The performance improving agent is used that contains stearoyl inulin, thioacetamide and allyl isothiocyanate in a weight ratio of 1: 1 to 10: 0.1 to 1, has excellent fluidity and constant strength, has excellent durability, and is harmful. The present invention relates to an eco-friendly grout composition for filling of one-component type that not only does not discharge components, but also absorbs and blocks harmful components, and a method of repairing and filling old closed pipes and joints using the same.
