Time To Corrosion Of Reinforcing Steel In Concrete Slabs

Download or read book Time-to-corrosion of Reinforcing Steel in Concrete Slabs written by Kenneth C. Clear and published by . This book was released on 1976 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 NaC1 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. This report, Volume 3, presents the results of evaluations of conventional concretes and those materials and techniques which "looked good" in the initial report. 830 daily saltings were applied prior to this evaluation.
