A concrete reinforcement material is provided to be cured without causing any freezing at low temperature when the reinforcement material is applied onto a concrete structure, and to improve workability and economic effect of repair and reinforcement construction. A concrete reinforcement material comprises a reinforcement material powder and a liquid phase in a weight ratio of 100:30. The reinforcement material powder includes 8.9-20wt% of light burned magnesia, 5-10wt% of magnesium chloride, 5-6wt% of calcium sulfoaluminate, 5-6wt% of anhydrite, 5-7wt% of general portland cement, 0.01-0.1wt% of aluminum metal powder, 1-6wt% of sodium nitrite, 1-6wt% of calcium nitrite, and 38.9-50wt% of sand. The liquid phase includes 25-35wt% of a resin emulsion, 21-26wt% of a resin emulsion which is urethane copolymer, 30-40wt% of purified water, 1-5wt% of ethylene glycol as an antifreezing liquid, 0.05-2.5wt% of an antiseptic, and 0.1-1.5wt% of texanol as a coalescent agent.
