REDUCTION IN CONCRETE-STEEL BOND WITH HORIZONTALLY EMBEDDED REINFORCEMENT

EXPERIMENTAL INVESTIGATIONS TO EXAMINE THE REDUCTION IN CONCRETE-TO-STEEL BOND WITH HORIZONTALLY EMBEDDED REINFORCEMENT RESULTING FROM THE SEDIMENTATION OF CONCRETES ARE REPORTED. CONCRETES OF THE SAME COMPRESSIVE STRENGTH BUT VARYING SETTLEMENT AND BLEEDING WERE USED WITH PLAIN, ROUND, SQUARE TWISTED AND DEFORMED BARS. THE GENERAL TREND OF THE PULL-OUT BOND STRENGTH RESULTS INDICATED THAT INCREASED CONCRETE SETTLEMENT IN ALL CASES LED TO REDUCED BOND OF RIGIDLY POSITIONED, HORIZONTAL BARS, EVEN WITH SMALL DEPTHS OF PLASTIC CONCRETE BENEATH THE BARS. THIS REDUCTION OF BOND WAS MORE MARKED WITH PLAIN ROUND AND SQUARE TWISTED BARS. /RRL/A/
