    摘要: PROBLEM TO BE SOLVED: To provide an anchor fixing material which can achieve anchor placing by man power at low temperature of ≤10°C and can obtain secure strength development. SOLUTION: The anchor fixing material is obtained by enclosing a hydraulic material comprising cement and calcium aluminate into heatron paper. The heatron paper has paper grain. The hydraulic material may comprise an alkali metal carbonate, a water reducing agent, a water holdable material and fine aggregate. The anchor fixing material is used for an anchor for fixing a falling stone protection net in a slope. The anchor fixing material is immersed into water, the anchor fixing material is filled into a bore, an anchor is press-fitted therein, and the anchor fixing material is destroyed.
