SummaryThe Project MAPMIT proposes the development of a method for the repair or retrofitting of infrastructure of transport (tunnels, walls and bridges) with a sprayed poyfunctional cementitious material (mortar or concrete) in a single layer. Air Jordan 7 Retro It also considers the development of new techniques to monitor the short and long-term evolution of properties of the sprayed material. soldes timberland To achieve this goal, the project is devided in three research lines: developments of materials, development of monitoring techniques and development of design tools and real-scale applications. Adidas Zx 700 pas cher homme In the first research line, different alkali-free set accelerator admixtures and other admixtures will be evaluated. Jake Arrieta Authentic Jersey This study will help to identify the main factors that govern the short-term development of properties of the sprayed material. Likewise, the incorporation of water-tightening agents and industrial byproducts such as recycled aggregate and EAF Slag will be evaluated. adidas y3 homme In the second research line, techniques based on the thermal evolution or ultrasound pulse velocity will be used for a very short-term prediction of mechanical properties using wireless equipment. nike scarpe 2017 Moreover, new methodologies will be proposed for the simplified evaluation of the shear strength and energy absorption, based in the Barcelona test. In addition to that, the viability of incorporating ferromagnetic alloys to give the sprayed material sensoring capabilities will be assessed. new balance The third research line will cover the development of constitutive equations for the structural design of the cementitious sprayed material. In this sense, models will be developed or adapted to account for the shear behaviour, creep and the bond between the sprayed material and the substrate. chaussures adidas Based on this models, a numerical tool will be developed for the design of the repair taking into account the coupled behaviour of the existing structure and the retrofitting layer.
