An Experiment on Bond Properties of Reinforcements Embedded in Ultra High Performance Concrete

Abstract:

Researches on Ultra High Performance Concrete (UHPC) have been conducted worldwide owing to its outstanding durability and strength performances compared to normal concrete. This paper experimentally investigates the bond properties of reinforcements embedded in UHPC using direct pull-out tests. The specimens were prepared for various compressive strength levels of 120, 150, and 180MPa, diameters of reinforcements of 13, 16, 19, 22 and 25mm, cover to bar diameter ratios and bonded lengths. The influences of each test variable on bond properties are examined and may be a useful data for design and analysis of UHPC structures.
