Evaluation of Adhesive Bonding between Steel and Concrete
At present adhesive bonding as an alternative to mechanical connectors does not belong to the standard practice in structural applications of the building and construction industry. Therefore the scope of this study is to experimentally investigate the behaviour of adhesively bonded joints between steel and concrete. The main attention was focused on shear stressed; tension stressed and combined stressed connections. To study the typical characteristics of adhesives in combination with steel and concrete different high-strength polyaddition curing adhesives, one polyurethane and two epoxy adhesives, were examined in this study. All tests were conducted at room temperatures. Also different aggregates for concrete such as crushed stone and round edged gravel were used. To promote a good adhesive bond cleaning and pre-treatment of the surface prior to bonding is of outmost importance. Therefore different pre-treatments for steel and concrete surfaces and their effect on the load behaviour and deformation capacity were considered. The concrete surfaces were used as grit-blasted and cut with a diamond saw. The steel adherents were grit-blasted and coated with primer prior to bonding.
