Time-to-Corrision of Reinforcing Steel in Concrete Slabs. Vol 1. Effect of Mix Design and Construction Parameters
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 wetting with a 3 percent NaC1 solution. Surface revibration and the use of chromate and silicone admixtures were investigated. Membrane, polyethlene sheet and wet burlap curing procedures were included. Surface protective treatments included boiled linseed oil and stearate. Special treatments studied were polymer-impregnated concrete, permanent steel bridge deck forms, galvanized reinforcing steel, latex-modified concrete, epoxy-modified concrete, a low water-cement ratio portland cement concrete overlay, an expanded pumice additive, and ferro-cement. An evaluation of the electrical half-cell corrosion detection technique was also performed. (Modified author abstract) Portions of this document are not fully legible.
