Experimental Study of Environmental Conditions on In-Situ Engineered Cementitious Composites-Steel Deck Interface
Source abstract
Abstract
In this study, engineered cementitious composite (ECC) was used as a deck paving for long-span bridges. The feasibility of using an epoxy adhesive to achieve wet-bonding between a steel deck and cast-in-place ECC was evaluated. The shear and pull-off tests were conducted to evaluate the effects of freeze-thaw cycles and hydrothermal aging on interfacial properties. The test results indicate that the interfacial strength decreases with an increase in the number of freeze-thaw cycles and the duration of hydrothermal aging. Based on an inclined shear test, a criterion for interface failure under the combined action of shear and compression is also proposed. Wet-bonding technology might promote the application of ECC in the surfacing system for orthotropic steel deck bridge and further extend the service life of a bridge structure.
