Cracking and fluid transport in coated and noncoated carbon fabrics in fabric reinforced cement-based composites
This paper provided a summary of recent experiments performed on paste specimens containing non-coated and coated carbon fabrics. While similar crack width and number of cracks observed for the coated and non-coated specimens, the non-coated carbon fabrics wet rapidly after samples were ponded with solution when compared with the coated fabrics. The rapid ingress of water in the non-coated bundles can be attributed to movement of the fluid along the filaments through the open porosity in between them. Therefore, when using fabric with yarns having multifilament nature as reinforcement for cement matrices there is a need to consider the ability of the liquid transport along or through the fabric. Based on this work it can be concluded that fabrics with uncoated bundles may be problematic from a durability point of view. Further work is needed to compare these insights with mechanical behaviour of coated and non-coated fabric systems made from bundles in order to optimally design textile reinforced concrete elements.
