Abstract
PURPOSE: To protect a reinforced concrete structure from a toxic material, chlorine, in sea water by a method wherein an impermeable film is formed between a plurality of cement material panels. CONSTITUTION: Cement material panels 2 and 2' are laminated together and a impermeable film 3 is nipped between material surfaces. Since the impermeable film 3 is protected between the cement material panels 2 and 2', impact damage due to aggregates during placing of depositing concrete or damage due to sand in sea water wave and a coarse floating substance even after the execution of a work are not caused. Thus, penetration of chlorine ions in sea water is blocked for a long period by the impermeable layer.
