<p>PURPOSE: To provide an anticorrosion concrete molding having an enhanced adhesiveness of a plastics layer eringing about anticorrosion property, a simple manufacturing process and inexpensive manufacturing cost, a short period of manufacturing, and a high anticorrosion property. CONSTITUTION: A concrete material and flaky plastics material are mixed. The mixture is made into a tubular shape by imparting a centrifugal force, and a part of the flaky plastics material is exposed on the entire inner peripheral surface of the tube through the difference in each specific gravity. Liquid curable plastic 23 are supplied into the inside of the tube so as to shield the inner peripheral surface of the tube with the plastic 23 through a centrifugal force. Then, the concrete material 21 and the curable plastic 23 are cured.</p> |
