The present invention relates to a grout composition for a cement mineral-based ground work, and the gel time of a liquid grout composition is simplified without being accompanied by significant fluctuations in basic properties of the grout composition such as leaching properties, strength and durability after hardening, etc. It is precisely controlled, suppresses material separation of the cement suspension, and secures the strength and corrosion resistance of the hardened injection material by utilizing industrial by-products. Through the present invention that can easily control the gel time of the grout composition, it is possible to precisely control the penetration area in the ground of the grout composition, thereby securing the construction accuracy, preventing unnecessary material loss, and , It can prevent environmental pollution by inhibiting short-term material leaching. |
