Abstract: Provided are an energy-saving and environment-friendly non-autoclaved pipe pile concrete material with high impact resistance, and a preparation method thereof. Raw materials of the concrete include cementing material, sand and gravels, modified rubber fiber, water reducer and water. The rubber fiber comes from waste tires. The cementing material includes cement, slag powder and silicon powder. A content of the cementing material in the concrete is 400-500 kg/m3. A water-cement ratio is 0.19-0.22. A specific surface area of the slag powder is 400-450 m2/kg. A content ratio of the slag power to the whole cementing material by mass is 25-40%. A specific surface area of the silicon powder is 15-30 m2/kg. A content ratio of the silicon power to the whole cementing material by mass is 5-10%. The modified rubber fiber is obtained by making the rubber fiber undergo shallow carbonization and soaking the obtained rubber fiber with a modifier.
