Title: Effect of Admixtures on Electrolytic Corrosion of Steel Bars in Reinforced Concrete
Author(s): Yasuo Kondo, Akihiko Takeda, and Setsuji Hideshima
Publication: Journal Proceedings
Appears on pages(s): 299-312
Abstract:Describes experimental research on the effects of ad- mixtures, fly ash and CaCl2 with and without calcium lignosulfonate, on the electrolytic corrosion of reinforcing steel embedded in 5 7/8-in concrete cubes. The reinforcing steel was subjected, as anode or cathode, to direct current of 5, 10, and PO v, or to alternating current of PO v for 28 do S s, 3 hr each day. mall amounts of C&12, less than 1 percent of cement by weight, caused no harmful reaction under direct current of less than 10 v, and when CaCl2 and calcium lignosul- fonate were used together, the corrosion tendency was alleviated considerably even under direct current of PO v. Alternating current of PO v caused no corrosion in concrete containing the admixtures.
