Abstract
The 15,7 mm diameter strands are most commonly used in prefabrication of pretensioned concrete elements. These elements are widely casted on high-strength and high-performance concretes in order to allow prestress as early as possible. To investigate the concrete-steel bond between high performance concrete (HPC) and 15,7 mm diameter strands research program was developed in Cracow University of Technology. To realize the program, a special tensioning bed was constructed and the concrete specimens for tests were casted under tensioned strands. This study develops new methodology for quantifying the bond of the 15,7 mm prestressing steel strand in PC members based on the results of the experimental tests. The results made it possible to assess qualitative and quantitative influence of Hoyer’s effect on the concrete bond to the prestressing seven-wire strand.
