Abstract
A formulation for blending with raw concrete to form an admixture wherein a concrete plasticizer and migrating corrosion inhibitors are blended with concrete prior to pour. The plasticizer enhances the ability of the concrete to be worked and to be properly finished, and the migrating corrosion inhibitors provide protection of concrete reinforcements such as rebar against corrosion.
