ABSTRACT
The considerable increment in use of Fabric Reinforced Matrix (FRM) strengthening systems in recent years has led to the need of investigating their durability when exposed to long-term actions. Single lap shear tests were performed on concrete and masonry specimens reinforced with different types of fabrics embedded in an inorganic matrix. A new test setup was developed with the aim of applying a sustained load for up to six months simultaneously to considerable amounts of specimens under the same controlled temperature and relative humidity conditions. The paper will describe the proposed setup and the instrumentation. It will also describe the results in terms of measured displacements for clay and natural stone masonry as well as concrete reinforced with fabrics made of different materials. The experimental campaign is part of an ongoing extensive assessment plan for the analysis of the durability of fabric reinforced inorganic matrix composites.
