An ultrahigh-strength cement-based grouting material comprises cementitious materials, mineral and active admixtures, super dispersing agents, composite expanding agents, water-retaining agents, a stabilizer, lubricating agents, a flexibilizer and coagulation agents. The ultrahigh-strength cement-based grouting material comprises, by weight, 550-650 parts of the cementitious materials, 100-200 parts of sand, 100-200 parts of the mineral and active admixtures, 5-8 parts of the super dispersing agents, 50-80 parts of the composite expanding agents, 0.3-0.8 part of a defoaming agent, 0.5-3 parts of the flexibilizer and 0.5-1.5 parts of the coagulation agent. According to the cement-based grouting material manufactured in the method, material components are simple, production is convenient, the cement-based grouting material has all the advantage of common grouting material and has the most remarkable advantage of being ultrahigh in strength, and the compressive strength of the cement-based grouting material is over 100MPa.
