Experimental study on the durability of polymer‐impregnated basalt textile applied as concrete reinforcement

Abstract

AbstractThis paper presents an experimental study on the durability of polymer‐impregnated basalt textile considering the effects of impregnation material, corrosion temperature, and corrosion solution. The variations in tensile strength, elastic modulus, surface condition, and failure mode were examined. Furthermore, a prediction model for the tensile strength degradation of basalt textiles was proposed. The experimental results showed that the tensile strength degradation of the textile was significantly influenced by the impregnation materials. The epoxy resin/acrylic emulsion‐impregnated textiles had superior durability to the styrene‐butadiene latex/vinyl resin‐impregnated textiles. As the temperature increased, the tensile strength decreased, whereas the variation in the elastic modulus was insignificant. In addition, the tensile strength of the weft textile degraded slightly faster than that of the warp textile owing to the larger contact area with the corrosion solution for the former. The saline–alkaline solution was more aggressive than the alkaline solution for the impregnated textiles owing to the corrosion caused by the combination of alkaline hydroxide ions and salt chloride ions in the former. The proposed model to predict the strength degradation considering both the aging time and temperature effect is in good agreement with the experimental results, which can be used to predict the long‐term strength of basalt textiles used as concrete reinforcement in real engineering applications.
