Abstract:
The research project "Textile Reinforced Concrete-Development of a new Technology" at Aachen University (RWTH Aachen) is investigating basic mechanisms regarding bond, durability and load-carrying capacity of textile reinforced concrete. One central task within the project is the development and optimization of a matrix which offers chemical compatibility with the textile materials (alkali resistant glass fibres) as well as a suitable workability, rapid hardening, and high early strenghts, for planned production processes respectively. New matrix systems have been composed which offer a lower potential for alkaline attack of the glass fibres due to their chemical composition. As these fine grained concretes differ significantly in composition from ordinary concrete, structural properties like porosity, permeability and diffusion coefficients have been determined for the different binder systems to investigate durability aspects. Time dependence as well as the influence of different storing conditions and carbonation of the fine grained concrete have been considered.
