The invention relates to the technical field of a cement-based material, in particular to a high-ductility cement-based material. The high-ductility cement-based material is prepared from silicate cement, coal ash, quartz sand, water, water reducing agent, thickening agent, PVA fibers and concrete expanding agent, and the weight percent of each component in the material to the silicate cement is as follows: 1.0 to 2.5 percent of coal ash, 0.8 to 1.2 percent of quartz sand, 0.8 to 0.85 percent of water, 0.005 to 0.05 percent of water reducing agent, 0.001 to 0.003 percent of thickening agent, 0.08 to 0.12 percent of concrete expanding agent, and the total volume ratio of the PVA fibers is 0.005 to 0.025 percent. The high-ductility cement-based material has good mobility, can basically reacha self-flatting agent, and is excellent in mechanical properties, good in anti-freeze performance, good after being circulated for 300 times in a thawing manner, and applicable to a cold district; the material is good in waterproofness, the seepage resistance grade of the material is 12, and the 28-day carbonization test depth is 12 mm; impact resistance and shock resistance are good; and the high-ductility cement-based material is resistant to the radiation of ultraviolet rays, and free from aging and failure at a low temperature.
