Накратко на български

Нови системи от естествени влакна и варови разтвори се изследват за укрепване на зидани сгради. Тези технологии намаляват разходите за ремонт, ограничават използването на енергоемки материали и помагат за опазването на историческите обекти.

GREen Advanced TEchnologies for the Retrofitting of masonry Structures

1. The pandemic caused some delays to our experimental programme and some of the results are still being finalised. 2. The development of NTRM strengthening solutions specific for masonry structures in terms of both structural compatibility and performance can considerably reduce the costs associated with the strengthening and rehabilitation of the existing building stock. In addition, the application of NTRM systems does not require trained labour, thus making this technology suitable for upgrading deficient buildings and infrastructure not only in Europe, but also in developing and underdeveloped countries. NTRM-based systems will also provide optimal solutions for key heritage structures, for which compatibility with the substrate and full reversibility of the intervention are paramount. The exploitation of natural fibres and lime based mortars will also limit the use of energy-intensive resources (advanced fibres, polymers and cement) and potentially boost local economies. The outcome of this work will contribute to achieve a more sustainable construction practices, reduce waste production and pressure on raw materials, and improve resource energy efficiency. Research. To continue to grow our research ambition, activity and excellence and to enhance our reputation for research excellence from fundamentals to application. Deliver on our strong REF position. Grow our activity to help mitigate other in year effects. Environment. To foster the collegiate and caring nature of the department. With focus on our individual and overall well being. Support and encourage all to achieve their potential, recognise and appreciate the need for focus on areas of excellence and the value of this in the overall contribution. The project has studied a novel strengthening solution that uses natural fibre meshes embedded in an inorganic lime-mortar matrix. The new system will provide a more sustainable and cost‐effective alternative to both traditional methods and advanced composite systems and will provide a more reliable solution that can be engineered to meet the specific performance criteria of masonry buildings. In addition, this NTRM strengthening system has been compared to the more spread FRCM strengthening system, such as SRG and BTRM.

Цел на проекта

Unreinforced masonry (URM) buildings constitute more than 70% of the existing building stock worldwide and make up the vast majority of the world’s cultural and architectural heritage. Although masonry has proven to be a highly versatile and durable construction material, much of the existing building stock in Europe and developing countries are non-engineered URM buildings, often built with weak materials and following poor construction practices. As a result, the majority of the existing building stock is in dire need of structural rehabilitation and strengthening. Traditional strengthening and rehabilitation techniques include grout or epoxy injections, crack stitching, surface overlays with mesh-reinforced concrete, chicken-wire or reinforced plaster, reinforced concrete jacketing as well as external/internal post tensioning. However, all of these techniques can affect significantly the dynamic response characteristics of the structure and can be costly, labour-intensive and highly obtrusive. In recent years, the use of advanced composite materials in civil engineering applications has increased exponentially, and the various retrofitting solutions that have been developed based on the implementation of these materials have proven to be very effective. However, the high performance of these advanced materials would not be effectively exploited on the less demanding masonry structures and the high material and installation costs would render them prohibitive in most European and developing countries. The proposed project aims to develop a novel strengthening solution that uses natural fibre meshes embedded in an inorganic lime-mortar matrix. The new system will provide a more sustainable and cost‐effective alternative and will provide a more reliable solution that can be engineered to meet the specific performance criteria of masonry buildings.
