BOND STUDIES ON HOT DIP GALVANIZED REINFORCEMENT IN CONCRETE

BOND STRENGTHS OF HOT DIP GALVANIZED EINFORCING BARS WERE INVESTIGATED IN SHORT-TIME TESTS. INFLUENCE OF THE CHROMATE CONTENT IN THE CEMENT, CHROMATE ADMIXTURE TO THE FRESH CONCRETE, AND CHROMATIZING OF THE GALVANIZED BARS WERE STUDIED IN PULLOUT TESTS AND TESTS OF REACTIVITY OF THE ZINC COATING IN CONCRETE. THREE BRANDS OF NORWEGIAN STANDARD PORTLAND CEMENT, TWO OF WHICH HAD A RELATIVELY LOW CHROMATE CONTENT, WERE TESTED. FOR ONE OF THE CEMENTS WITH LOW CHROMATE CONTENT, IT WAS FOUND THAT A GREAT REDUCTION IN BOND STRENGTH RESULTED WHEN GALVANIZED BARS WERE USED. RELATION BETWEEN THE CHROMATE CONTENT IN THE CEMENT AND BOND REDUCTION AND REACTIVITY OF THE ZINC COATING COULD BE STATED. A CHROMATE ADDITION TO THE FRESH CONCRETE AND ESPECIALLY A CHROMATIZING OF THE GALVANIZED BARS ELIMINATED THE REDUCTION BOND STRENGTH. /AUTHOR/
