Assessment of masonary flexural bond strength
This thesis presents the results of an experimental assessment of masonry
flexural bond strength. Since there is insufficient experimental data on key
performance requirements for bond between units and mortar, investigations into
the development of bond and flexural strength across a range of masonry units for
both traditional and new mortar types, reflecting the recent changes in European
standards, were conducted.
In order to demonstrate the performance of bond between unit and mortar, the
latter ranging from weak to strong, a practical bond wrench testing rig was
developed for use with couplets and stack bonded prisms. This involved carrying
out investigations into existing designs and revaluations using up to date
modelling techniques. The result is a new bond wrench applicable for use in
laboratories and on site.
