Through adhesive surface treatment for bonded joints
Through adhesive surface treatments have been defined as pretreatments for adhesive bonding where the adherend surface is physically attacked under a covering layer of uncured adhesive. In addition to the usual benefits associated with physical pretreatments, there is potential for novel chemical …

Recommendations for Surface Treatment for Virginia Inverted T-Beam Bridge System
This thesis investigates the impact of interface surface treatment methods for use in the Virginia Inverted T-Beam bridge system. The specific system consists of precast beams with thin bottom flanges placed next to one another, with a cast-in-place slab on top. Previous research has shown that the …
