IMPROVED CORROSION INHIBITING FORMULATIONS WITH CALCIUM NITRITE. |
摘要 |
<p>An admixture for cement compositions is provided which contributes both anodic and cathodic corrosion inhibition, and the cement compositions containing such additives. The cement additive is a combination of an anodic corrosion inhibitor such as calcium nitrite, and a cathodic corrosion inhibitor such as calcium stearate or other fatty acid. The mixed inhibitors in accordance with the invention provide as good or better corrosion inhibition than does calcium nitrite when used alone.</p> |
