The invention relates to a cementitious material containing regenerated brick powder and a cement-based material. The cementitious material comprises cement and regenerated brick powder, in percentage by weight, the percentage content of the cement is 70%-100%; the percentage content of the regenerated brick powder is 0%-30%; the preparation method of the regenerated brick powder comprises the following steps: step 1, preparing waste brick powder; the waste brick powder is heated to the temperature T, constant-temperature treatment is conducted for 2-8 h, then the temperature is reduced to the room temperature, screening is conducted, and the waste brick powder is obtained; the temperature T ranges from 100 DEG C to 1000 DEG C; according to the invention, not only is the use amount of cement in the cementing material reduced, but also a new application way is provided for recycling of the waste brick powder, and the application range of the regenerated brick powder is expanded. 本发明涉及一种包含再生砖粉的胶凝材料及水泥基材料，所述胶凝材料
