EVALUATION OF ALUMINUM-COATED WIRES AS REINFORCEMENT FOR ARTICULATED CONCRETE MATTRESSES; SUPPLEMENTARY COMPARATIVE TESTS OF STAINLESS AND COPPER-CLAD STEEL WIRES

Abstract

Tests were conducted to determine galvanic effect between stainless steel and copperweld wires, and effect on tensile strength of copperweld wire of pinholes and the corrosion in pinholes. In the galvanic-effect tests, stainless-steel and copperweld-wire specimens were tied together and exposed (completely immersed, partially immersed, or alternately immersed and dried) to either 5000 ppm NaCl (pH 7) or dilute H2SO4 buffered at pH 5, maintained at 100F. Degree of corrosion was determined after 30 to 270 days. Galvanic effect on copperweld was to reduce corrosion for complete or partial immersion in either solution, and to increase corrosion for alternate immersion in either solution. Galvanic effect on stainless steel was very slight.
