The high-ductility concrete is prepared from the following components in percentage by mass: 47 to 50 percent of quartz sand, 36 to 38 percent of cement, 5 to 7 percent of mineral powder, 3 to 5 percent of coal ash, 2 to 3 percent of silica fume, 0.5 to 0.8 percent of fiber, 0.4 to 0.6 percent of rubber powder, 0.1 to 0.3 percent of a thickening agent, 0.05 to 0.08 percent of an expanding agent, 0.02 to 0.04 percent of a water-retaining agent, 0.02 to 0.04 percent of a water reducing agent, 0.02 to 0.04 percent of a flatting agent, 0.02 to 0.03 percent of an air entraining agent and 0.01 to 0.02 percent of an accelerator. The concrete has the effects of high toughness, high crack resistance and high damage resistance, the ultimate tensile strain capacity is more than 200 times of the strain capacity of common concrete, and the concrete has a strain hardening effect during stretching.
