description The invention discloses a high toughness cement-based material and a preparation method thereof. The high toughness cement-based material is prepared from the following raw materials in parts by weight: 10 to 20 parts of styrene-butadiene emulsion, 30 to 50 parts of portland cement, 15 to 25 parts of coal ash, 7 to 15 parts of composite reinforced fiber, 6 to 14 parts of silica fume, 4 to 10 partsof mica powder, 1 to 5 parts of dispersing agent, 2 to 5 parts of water reducing agent, 0.5 to 3.5 parts of thickening agent and 12 to 18 parts of water. According to the high toughness cement-basedmaterial disclosed by the invention, through compound mixing of the styrene-butadiene emulsion and the composite reinforced fiber, meanwhile, the flexibility of concrete matrix and the bonding strength of the composite reinforced fiber and concrete after concrete cracking are increased so that the purpose of reinforcing the toughness of the concrete is achieved, the styrene-butadiene emulsion canbe dehydration hardened int
