Method of preparing and using concrete reinforcing elements

Claim 2

The method of claim 1 wherein the resulting coated reinforcing elements are placed under tension and thereafter cast into said concrete.

Claim 3

at least partially imbedding the resulting coated elements in concrete and permitting curing of the concrete; wherein said pulverulent metal is present in an amount not substantially above about 5,000 milligrams per square foot of element surface and is selected from the group consisting of zinc, aluminum, magnesium, manganese, mixtures thereof and alloys of same, and with the proviso that there is present in the coating composition, when said composition contains above about 5 weight percent miscible water, basis total weight of liquids in said medium, below about 100 grams per liter of organic component of at least one non-aromatic carboxylic compound selected from the group consisting of: A. carboxylic acids, anhydrides thereof, where such exist, and ammonium salts thereof where such exist, wherein such acids are selected from the group consisting of saturated and unsaturated monocarboxylic acids, dicarboxylic acids, and polycarboxylic acids having at least three carboxyl groups per molecule, and mixtures thereof; and, B mixtures of said carboxylic compound with not substantially above about 40 weight percent, basis the weight of said organic component, of additional compound selected from the group consisting of succinimide, acrylamide, aspartic acid, and their mixtures, there being in said organic component not more than 90 weight percent, basis total weight of said component, of succinic acid.
