Utvärdering av nytt reparationssystem för tegelbalkar.

- Abstract (Swedish)
- In the 1940-ies curtain walls were introduced, i.e. brick walls that do not have any bearing function but served as a front material. Horizontal reinforcement was used in this kind of walls, partly over and under openings or, in undisturbed wall fields, every 5-6th bed joint. In this work the tensile bond strength of mortar joints repaired with an injection tool and a manual method respectively is examined. The influence of mortar and brick type is tested. Four different fasteners are tested with respect to tensile capacity. Masonry specimens with three bricks are used – with massive and perforated bricks and three different mortar types. The tests show that massive bricks result in mortar joints with higher bond strength than perforated... (More)

Four different fasteners are tested with respect to tensile capacity. Masonry specimens with three bricks are used – with massive and perforated bricks and three different mortar types. The tests show that massive bricks result in mortar joints with higher bond strength than perforated bricks.
None of the four tested fasteners are entirely acceptable from a technical point of view. Hence, recommendations for an optimal fastener for repair of damaged masonry beam are presented. (Less)
