- Abstract
- The anchorage length needed for textile fabrics as reinforcement within a fine-grained concrete matrix was determined based upon specific filament yarn pull-out tests. The purpose of this research was to eliminate the possibility of failure due to fabric pull-out from the matrix in practical applications. Therefore, a new test set-up was developed, which offers the possibility for a quick and direct determination of the anchorage length. Several textile fabrics made of alkali resistant glass (AR-glass) fibres, as well as carbon fibres were therewith tested. Findings indicated that conventional AR-glass fabrics required large anchoring lengths, and, it’s another fact to consider, that carbon fibres have a substantially higher strength than AR-glass fibres and different bond behaviour. The research further showed that an additional application of a polymer suspension coating to textile fabrics greatly increased the reinforcement’s resistance to pull-out.
