Time-To-Corrosion of Reinforcing Steel in Concrete Slabs. Volume 3. Performance After 830 Daily Salt Applications
The purpose of this investigation is to provide administrators and designers with factual data on which to base decisions on the type of protection to provide to bridge decks constructed in corrosive environments. Specifically, the objective is to determine the relative time-to-corrosion of reinforcing steel embedded in concrete slabs, fabricated from various mix designs and construction procedures when the slabs are subject to periodic setting with a 3 percent NaCl solution. One hundred and twenty-four, 4 ft. by 5 ft. by 6 in. reinforced concrete slabs were fabricated, cured, and placed in the outdoor exposure yard on elevated stands. Concrete covering the feasible range of mix designs were investigated. Clear concrete cover over the reinforcing steel was varied from 1 to 3 inches. Various finishing methods, curing procedures, admixtures, surface protective treatments and special new concretes were also included. This report, Volume 3, presents the results of evaluations of conventional concretes and those materials and techniques which 'looked good' in previous reports. 830 daily saltings were applied prior to this evaluation.
