Description du projet
Une nouvelle solution pour renforcer le béton
Renforcer et réhabiliter les structures en béton vieillissantes de l’Europe est une tâche complexe. En effet, plus de la moitié des travaux de construction réalisés chaque année consistent à rénover et à remettre en état des bâtiments existants afin de prolonger leur durée de vie utile. Les techniques de pré- ou post-contrainte sont les plus couramment utilisées pour renforcer le béton, mais elles présentent plusieurs limites (corrosion due à la tension, performances médiocres face aux charges sismiques et faible résistance au feu). Le projet IMPRESS, financé par l’UE, met au point une technologie appelée PAT (Pressure Activated Tendon) pour les structures et les bâtiments existants, qui permettra d’accroître la résistance aux charges sismiques et aux incendies, et d’améliorer les performances environnementales des bâtiments.
Objectif
Over 50% of the annual construction budget in Europe is spent on refurbishment and remediation of the existing structures in order to prolong their service life . Concrete, although strong in compression, is weak in tension: for this reason it needs help in resisting tensile stresses. Currently used systems that are generating compressing concrete are prestressing and post-tensioning. The limit of both techniques are tendons corrosion, scarce performance on seisminc loads and low fire resistance.
Gemini Impianti has developed a technology (PAT / Pressure Activated Tendon) that remove all the downsides of the currently know prestressing / post tensioning methods making also possible generate multiaxial simultaneous prestressing that can actually generate full prestressed nodes. The PAT, can be used in any size of concrete structure and it can be actually used on in situ construction and as well for improve the behaviour to seismic and fire loads of existing structures and building and can also contribute in improving environmental performances of buildings. The PAT techniques has been initially validated in lab test and against market requirements, receiving Letter of Interest from main Tendon producers in targeted markets (namely Laterlite SpA, Dayton Superior Inc, HG Group). Gemini is then fully committed in bringing this innovative solution on the market (that is valued USD 4.2 billion by 2025) and a preliminary investigation on overall investment needed has been carried out: the innovation project budget is assessed in €2,4M€, that will allow to reach 50M€ turnover at Y4 after project completion.
