The aim of the STRETCH project is to develop a hybrid structural-plus-energy retrofitting together with structural health monitoring tailored for masonry cultural heritage building envelopes. The innovative multifunctional system integrates textile-reinforced mortar with thermal insulation materials and strain/temperature fibre optic sensors. The proposed systemcan be instrumental both the assessment and conservation of cultural heritage buildings.
The use of a lime-based and cement-free mortar matrix for the design of the textile-reinforced mortar makes it compatible with the physical and mechanical characteristics of historic masonry. Fibre optic sensors integrated into the textile and embedded into the textile-reinforced mortar composites will provide distributed strain/temperature measurement. Capilary tubes inserted in the textile reinforcement will improve the energy efficiency of the envelope (this functionality is explored uder the international project SEP+)
