SOLUTION: The windbreak fence comprises a hardened material of a mixture composed of at least cement, pozzolanic fine powder, a fine aggregate having≤2 mm maximum particle diameter, a water reducing agent and water. The windbreak fence may comprise the mixture and inorganic particles having 2,500-30,000 cm<SP>2</SP>/g Blaine specific surface area and a Blaine specific surface area larger than that of the cement. The inorganic particles consist of inorganic particles A having 5,000-30,000 cm<SP>2</SP>/g Blaine specific surface area and inorganic particles B having 2,500-5,000 cm<SP>2</SP>/g Blaine specific surface area. The windbreak fence comprises the mixture and at least one or more kinds of fibers selected from the group consisting of a metal fiber, an organic fiber and a carbon fiber.
