The present invention relates to a grouting composition for reinforcing anchor, and the objective of the present invention is to improve injection performance for a smooth injection process by composing the grouting composition for reinforcing anchor with silica, cement, a filling material, an expansion agent, a blocking agent for harmful materials, a dispersion agent, an enhancing agent, a retardant, a binder, and an antifoaming agent. To achieve the objective, the grouting composition to improve the fixing force and strength of the anchor comprises: 35-50 weight% of silica; 10-30 weight% of cement; 10-25 weight% of a filling material; 5-10 weight% of an expansion agent; 0.1-3 weight% of a blocking agent for harmful materials; 0.01-0.6 weight% of an enhancing agent; 0.01-0.5 weight% of a dispersion agent; 0.01-0.4 weight% of a retardant; 0.03-0.2 weight% of a binder; and 0.01-0.1 weight% of an antifoaming agent. The components of the grouting composition are selected in such a way that the ratio of each component needs to be 100 weight% in total. |
