Durability aspects of AR-glass-reinforcement in textile reinforced concrete, Part 1: Material behaviour

Abstract

Textile reinforced concrete (TRC) is an innovative material for thin-walled, structural elements with a high load-bearing capacity. For a safe design of TRC load bearing structures ambitious investigations were carried out to predict the timedependent loss of strength of the AR-glass reinforcement embedded in fine grained concrete as a consequence of weathering. In the present paper possible reasons for the loss of strength of state-of-the art AR-glass reinforcement in nowadays cementitious mixtures are described and their relative importance is discussed, based on new results. In the accompanying paper (part 2), these results are used to present a durability model under complex weathering conditions.
