Abstract
An anti-corrosive additive composition is provided that includes an alkali-based salt of dioic acid and a defoamer agent. The defoamer agent is generally selected from the group consisting of a polyether modified polysilicane, a tri-alkane phosphate, a tri-alkene phosphate, and mixtures thereof. The anti-corrosive additive is particularly adapted for use with concrete compositions, e.g., a concrete composition that includes at least one rebar.
