A Study on the Bond Strength between High Performance Concrete and Reinforcing Bar
As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...
متن کاملEffect of Reinforcing Bar Contamination on Steel-Concrete Bond During Concrete Construction
Synopsis: During concrete construction, form oil, bond breaker, concrete splatter and other types of contaminants often contaminate reinforcement. Current specifications and quality control measures require the removal and clean up of these contaminants before the placement of concrete due to a concern of a reduction in bonding capacity. This is costly, labor intensive, and may not be necessary...
متن کاملBond of High Strength Concrete with High Strength Reinforcing Steel
This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...

متن کاملEffect of thermal recycling of metal brackets on shear and tensile bond strength.
AIM The study was undertaken to measure the changes within the mesh pad associated with reconditioning process, measure the bond strength of new and reconditioned orthodontic brackets and correlate the changes in mesh strand diameter with changes in bond strength. MATERIAL AND METHODS 120 clinically normal premolar teeth extracted for orthodontic reasons, were divided equally for bonding with...
