The invention provides anti-fracture seepage-proofing cement. The anti-fracture seepage-proofing cement comprises raw material ingredients and cement powder grinding materials. The raw material ingredients include low-magnesium limestone, high-magnesium limestone, sandstone and iron powder. The cement powder grinding materials include clinker, a mixed material, silica fume and gypsum. During cement production, a certain amount of high-magnesium stone with expansibility is added in the raw material matching process, and the cement shrinkage problem is solved. A certain amount of silica fume is added in the cement powder grinding process, gaps between cement particles are filled, and accordingly a seepage-proofing effect can be achieved. The anti-fracture seepage-proofing cement can be used for large-scale concrete pouring and underground projects, underwater projects and other projects with seepage-proofing requirements.
