RAPID REBAR CORROSION TEST. STRATEGIC HIGHWAY RESEARCH PROGRAM PRODUCTS. PROCEEDINGS OF A SPECIALTY CONFERENCE SPONSORED BY THE HIGHWAY DIVISION OF THE AMERICAN SOCIETY OF CIVIL ENGINEERS AND THE FEDERAL HIGHWAY ADMINISTRATION. DENVER MARRIOTT CITY CENTER HOTEL, DENVER, COLORADO, APRIL 8-10, 1991

Research to develop tests that can accurately predict the effects of deicing chemicals on the corrosion of steel in reinforced concrete structures is reported. The research includes the development and evaluation of a standard test specimen and the use of 3 deicing chemicals to determine the sensitvity of both corrosion potential and macrocell corrosion to molal ion concentrations ranging from 0.4 to 6.4. The standard test specimen consists of a No. 4 reinforcing bar embeded in a 1.18 in (930 mm) diameter, 4 in. (100 mm) long mortar cylinder. The mortar is made using portland cement, deionized water and standard graded Ottawa sand. Specimens cured in lime-saturated water reach a passive condition within 14 days. Based on limited test data using sodium chloride, calcium chloride, and calcium magnesium acetate, calcium chloride appears to be the most detrimental, followed in order by sodium chloride and calcium magnesium acetate.
