摘要： PROBLEM TO BE SOLVED: To provide a pier reusing method for reusing a structure that cannot exert functions of a pier due to its aging, deterioration, or the like, without crushing the same.
SOLUTION: In reusing the structure that cannot exert the functions of the pier 1, the pier reusing method comprised of the following steps is employed. In the first step, a steel pipe pile 2 is cut away from the pier 1 and superstructure work 10 formed of a floor slab portion 5, a beam portion 4, and a pile head portion 3 is removed. In the second step, the removed superstructure work 10 in its original condition or in a condition in which a new structure or a new object is added to the original superstructure work, is set on the ground, in the ocean, or in a river, to thereby form a new structure having new functions. Thus the pier 1 can be reused without crushing the same, and therefore dust or noise which is unavoidable when crushing is carried out, occurs, whereby a large load is not imposed on the environment.

摘要： PROBLEM TO BE SOLVED: To solve the problem that polarization resistance acquired by the linear polarization resistance method has often contained environmental resistance in its resistance value.
SOLUTION: A potential sweep is performed at a potential of approximately ±10 mV with respect to the natural potential of a reinforcing bar at a speed, which indicates an environmental resistance (at which the potential is swept very fast), and a potential sweep is performed at a speed, which indicates the sum of the polarization resistance and the environmental resistance (at which the potential is swept very slowly). On the basis of the difference between the acquired sum of the polarization resistance and the environmental resistance and the acquired environmental resistance, the polarization resistance is determined to compute a corrosion current density.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of preventing the corrosion of a steel material in a reinforced concrete structure easily applicable at a low cost, and the like.
SOLUTION: The method comprises the steps of placing a reinforcing steel structure composed of reinforcing bars in a concrete molding flask, kneading alumina cement, seawater, fine aggregate and coarse aggregate to make fresh concrete in a fluid-state, filling the fresh concrete in the molding flask to embed the reinforcing structure and curing. Corroded surface area of the reinforcing bar (coverage 20 mm, 40 mm, 70 mm) of the above sample ALS is smaller than that of tap water-formulated type ordinary Portland cement concrete PCW or tap water-formulated type alumina cement concrete ALS showing higher preventing effect on corrosion of reinforcing bar.
