Abstract

PURPOSE:To prevent the corrosion of concrete-reinforcing steel material at a low cost and efficiently, by cleaning the surface of the concrete-reinforcing steel material such as steel fiber, steel rod, by dipping it into an aqueous soln. contg. Cu and Sn, then by washing it with water and by drying it. CONSTITUTION:Steel fiber, or steel rod, a concrete-reinforcing material, is cleaned at its surface, then it is dipped into an aqueous soln. contg. Cu and Sn to form alloy plating film contg. Cu and Sn in a ratio the same as that of tin bronze, that is, 2-35% Sn, preferably <10% Sn. Then the reinforcing steel material is washed with water, dried and is painted with quick-drying lacquer in order to cover very fine gaps formed in the plated layer thereby protecting the surface of the reinforcing steel material. By this method, Fe dissolves in the aqueous soln. and Cu and Sn deposit on the surface of the steel material in accordance with the ionization tendencey, in addition, the metal coating formed by the interaction of Cu and Sn adheres closely to the iron matrix.
