Abstract

A corrosion-inhibiting admixture comprising: i) one or more waterproofing agents; ii) one or more mono-, di- or trialkanolamines; and iii) optionally, one or more additional corrosion-inhibiting agents, with the proviso that if the waterproofing agent is capable of forming a salt with ii) and/or iii), then at least a portion of i) and ii) and/or i) and iii) are present in the admixture in their salt form in combination with each other, which admixture is effective in controlling chloride-induced corrosion of iron or steel reinforcing members in place in concrete without substantially interfering with the ability of the concrete to entrain air.
