Abstract
Discusses the bond strength between a high-performance concrete (HPC, having a 28-day strength of 95 MPa) and reinforcing bars. This was mea sured in a series of beam tests in which the concrete type (HPC and or dinary concrete), reinforcement diameter (between 10 and 25 mm), and r einforcement surface condition (smooth and deformed bars) were varied. In general, concrete-reinforcement bond strength increases with the t ensile strength of the concrete, and at a higher rate with smaller rei nforcement (a more marked scale effect).
