PROBLEM TO BE SOLVED: To maintain good fluidity when anchor elements are driven into a hollow portion or the like formed by drilling and prevent escape of a fixing material composition from the inside of the drill, and tunnels such as roads, railways, and water conduits. An anchor element fixing material having excellent workability in applications such as a rock bolt method and a slope anchor method, a rapid-hardening cement composition for the fixing material, and an anchor element fixing method using the fixing material To do. SOLUTION: 100 parts of alkali metal carbonate, 5 to 40 parts of aluminate, 20 to 80 parts of inorganic compound, 5 to 30 parts of calcium aluminate, 0.1 to 5 parts of water retention material, oxycarboxylates 0. A quick-setting agent containing 01 to 2 parts, 3 to 20 parts in terms of solid content with respect to 100 parts of cement, and a fine aggregate having a particle size of 0.6 mm or less to 100 parts of cement A quick-hardening cement composition for anchor element fixing materials, contained in an amount of up to 90 parts. An anchor element fixing material comprising the composition. An anchor element fixing method using the fixing material. [Selection figure] None |
