Abstract: Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.

Abstract: Provided are a system and method for reinforcing and protecting a reinforced concrete structure in which a reinforced concrete structure is divided and corrosion factors of the divided cross-sectional regions are monitored to automatically supply a protection current to each of the divided cross-sectional regions, thereby actively performing protection of the reinforced concrete structure, and also, by adjusting the level of a protection current according to the progression of corrosion in each divided cross-sectional region of the reinforced concrete structure, power consumption required for protection is optimized and protection is effectively performed, and also by disposing a carbon fiber textile grid in the surface of the reinforced concrete structure to be employed as both a reinforcement member and an anode of the reinforced concrete structure, microcracking which may occur in concrete curing is inhibited and thus permeation of moisture or a chloride into the surface thereof is prevented.

Abstract: Provided are a textile reinforced cement composite for suppressing occurrence of slipping and a crack and a manufacturing method thereof. The textile reinforced cement composite for suppressing occurrence of slipping and a crack can suppress slipping between a textile grid reinforcement and a cement composite by using an angulated filling material mixed therewith when a textile reinforced cement composite having a textile grid reinforcement embedded in a cement composite is manufactured, suppress occurrence of a crack of the cement composite, suppress occurrence of a crack of the cement composite due to a fiber bridging reaction by using organic fiber mixed therewith, induce distribution of fine cracks, suppress degradation of fluidity of the cement composite caused by mixing of the angulated filling material by using a spherical binder and a chemical admixture added thereto, and suppress slipping between the textile grid reinforcement and the cement composite by using a fine powder binder having a predetermined particle size and mixed therewith.

Abstract: Provided are an anchor pin for placing shotcrete and fixing a textile grid and a method of constructing textile grid reinforced shotcrete using the same, wherein the anchor pin allows a textile grid reinforcement to be precisely disposed at a required position and, when shotcrete is placed, prevents a textile grid reinforcement from moving due to a driving pressure for precise construction so as to increase durability and safety of the concrete structure, allows primary and secondary shotcrete to be constructed while placing thicknesses thereof are visually checked so as to increase precision of construction, and allows the textile grid reinforcement to be disposed and fixed to accurately correspond to a shape of the concrete structure even when a lower portion of a slab, a wall, and a structure with a curved surface, such as a lining of a tunnel, are built.
