Mechanical Performance of Mineral-Impregnated TRC
摘要
Textile reinforced concrete (TRC) has been gaining attention in recent years on account of its excellent properties, such as, low carbon footprint, good mechanical properties etc. For increasing the utilisation of fibre filaments within the textile and thus fully exploiting the mechanical properties of TRC, polymer impregnation of fibre bundles/textiles has been used to allow the filaments to be bonded together as a single unit. However, the high temperature sensitivity of the polymer and its chemical incompatibility with the concrete matrix have limited the further development of TRC. Compared to the polymer, mineral-based materials can provide excellent compatibility with concrete matrix and stability under high temperatures, and therefore are emerging as an innovative impregnation material for textile reinforcement in TRCs. This paper presents preliminary studies conducted at the University of Birmingham in developing this technology and in assessing the mechanical performance of TRC composite made of these innovative reinforcements. The results show excellent efficiency of impregnation and a significant enhancement of the flexural response of TRC composites reinforced with mineral-based carbon yarns is achieved.
