Abstract
A corrosion inhibiting admixture for concrete is disclosed comprising a combination of organic (amines) and inorganic (nitrites) fractions that provide a synergistic effect when present at a specific ratio. Such a synergistic effect occurs when the amine:nitrite ratio (% by weight) is between 1.5 to 2.5 resulting in the admixture providing excellent corrosion inhibiting capabilities.
