Development of a textile reinforced concrete (TRC) to retrofit reinforced concrete structures

Development of a textile reinforced concrete (TRC) to retrofit reinforced concrete structures Repairing and strengthening concrete structures with carbon–epoxy composites is of considerable interest; however, there is room for improvement regarding existing methods like bonding of fibre reinforced polymer (FRP). The main objective of this study is to show alternatives to these FRP composites, such as textile reinforced concrete (TRC). Feasibility, performance and behaviour of TRC are examined. A parametric analysis conducted using an experimental approach focuses on the influence of the nature and configuration of the textile reinforcement, the textile reinforcement ratio of the TRC, the pre-impregnation product of the textile and the process for the contact moulding. This study enabled the development of a TRC suitable for repairing reinforced concrete beams by in situ contact moulding. The composite is made of a polymer-modified cementitious matrix reinforced with grids of alkali-resistant glass yarns that are pre-impregnated with a latex-based additive immediately prior to implementation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Environmental and Civil Engineering Taylor & Francis

Abstract

Repairing and strengthening concrete structures with carbon–epoxy composites is of considerable interest; however, there is room for improvement regarding existing methods like bonding of fibre reinforced polymer (FRP). The main objective of this study is to show alternatives to these FRP composites, such as textile reinforced concrete (TRC). Feasibility, performance and behaviour of TRC are examined. A parametric analysis conducted using an experimental approach focuses on the influence of the nature and configuration of the textile reinforcement, the textile reinforcement ratio of the TRC, the pre-impregnation product of the textile and the process for the contact moulding. This study enabled the development of a TRC suitable for repairing reinforced concrete beams by in situ contact moulding. The composite is made of a polymer-modified cementitious matrix reinforced with grids of alkali-resistant glass yarns that are pre-impregnated with a latex-based additive immediately prior to implementation.
