The investigations are focussed on reinforcement of multi-filament yarnsof alkali-resistant glass. When embedded in concrete, these yarns are not entirely penetratedwith cementitious matrix, which leads associated with the heterogeneity of the concrete andthe yarns to a complex load-bearing and failure behaviour of the composite. The main objec-tive of the work was the theoretical investigation of effects in the load-bearing behaviour ofTRC, which cannot be explained solely by available experimental results.
