Grout Material Composition and Reinforcement Methods Using Grout Material Composition and Anchor installed Sensor

摘要

The present invention, based on 100 parts by weight of cement, 5 to 30 parts by weight of calcium sulfoaluminate; 10 to 60 parts by weight of fine powder of blast furnace slag; 1 to 5 parts by weight of slaked lime; 1 to 10 parts by weight of sodium bentonite; 1 to 10 parts by weight of methyl methacrylate; 10 to 30 parts by weight of nano-ceramic particles; 1 to 10 parts by weight of fibers; 1 to 10 parts by weight of a dispersant; 0.1 to 2 parts by weight of a stabilizer; 0.1 to 3 parts by weight of surfactant; And it relates to a grout material composition comprising 0.01 to 10 parts by weight of a high performance water reducing agent, and a repair and reinforcement method using the same. The grout material composition and repair reinforcement method using the same according to the present invention obtain durability, bearing capacity, and/or water resistance, etc. during grouting for repair and reinforcement, and supplement the physical properties of the structure such as tensile strength, as well as the ground or structure. It has the effect of being strongly attached to extend the lifespan.
