Abstract: Cracks in cementitous materials can substantially increase fluid penetration. Fiber reinforcement can reduce the crack width in cementitious materials thereby reducing fluid transport. The extent of crack width reduction that can be expected is based on the physical properties of the fiber reinforcement and the uniformity of the fiber spacing. Textile fabric reinforcement provides substantial benefits in that the location and orientation of the reinforcement can be carefully controlled. As a result of the opportunities that fabric reinforcement provides, substantial research has been performed to better understand how textile fabric reinforcement improves the mechanical behavior under tensile, bending, shear and impact loadings. Less work has been reported to study the influence of textile reinforcement on fluid transport properties. This paper describes a series of experiments in which fluid transport was measured using the x-ray radiography in cracked cement paste samples that were reinforced with coated and non coated carbon fabrics. The results of this study show that if non-coated carbon fabrics are in contact with the solution they transport solution rapidly, while this is not the case in coated fabrics.
