Abstract

The strength durability of glass fibre reinforced concrete (GRC) remains a widely studied topic. Many have tried to identify the mechanisms leading to strength loss. Generally 3 main mechanisms are recognized: (1) chemical attack of the glass reinforcement due to the alkaline environment provided by the cementitious matrix; (2) embrittlement due to the growth of hydration products in the vicinity of the reinforcing inclusions and (3) static fatigue. This knowledge has lead to the development of several improved material combinations. Nevertheless, even when Alkali Resistant (AR) glass fibres, improved coatings, altered low alkaline matrices, etc. are being used, these GRCs are not immune to degradations. Therefore, during the design of GRC elements strength durability should already be taken into account. Within this paper some of the issues encountered during the modelling of the strength durability of GRCs will be discussed, with a focus on (candidate) strength durability models, modelling procedures, etc.
