The use of chemical bonds to fasten reinforcement bars in existing concrete structures has been widely developed in the previous years, showing in many cases higher bond values compared to cast in rebars due to better performance of the adhesive mortar. However, at elevated temperatures the concrete-adhesive bond tends to weaken endangering the construction under a fire situation. The paper presents...
An experimental investigation into the shear transfer across the brick mortar interface at different levels of applied pre-compression is reported. Direct shear tests are performed in the triplet test configuration on masonry made with a soft brick. The failure across the brick–mortar interface is progressive and is produced by a crack in the brick–mortar interface. The interface crack propagates...
