Methods and compositions for reclaiming concrete

An admixture for inhibiting chloride-induced corrosion in steel reinforcing in place in concrete comprises an O/W emulsion wherein the oil phase comprises an unsaturated fatty acid ester and ethoxylated nonyl phenol and the ester of an aliphatic carboxylic acid with a mono-, di- or trihydric alcohol and the water phase comprises a saturated fatty acid, an amphoteric compound, a glycol and a soap. The admixture is added to the concrete prior to placement.
