Steel Reinforced Concrete (RC) structures may need strengthening during their service life. Textile Reinforced Concrete (TRC) presents elevated mechanical behavior and low self-weight, presenting as a suitable alternative for strengthening RC elements. Polymeric-coated carbon fabrics present high mechanical properties but low thermal resistance. Mineral impregnations can increase the bond of carbon yarns towards cementitious matrices even at elevated temperatures. This work aims to assess the mechanical behavior of Mineral-Impregnated Carbon Fibers (MCF) fabrics TRCs. For this, MCF yarns with a cement-based (C) and a geopolymer (GP) suspension were produced. Both MCF yarns yielded high tensile strength and modulus of elasticity. The bond of the MCF yarns towards a cementitious matrix was evaluated through pull-out tests at different elevated temperature levels and compared to a yarn of a currently commercially epoxy-coated (EP) carbon fabric. The C-MCF yarn presented higher bond strength towards the matrix than the GP-MCF. At elevated temperatures, the bond between the EP yarn and the matrix became considerably weaker, while the MCF yarns could maintain a sufficient bond up to 300 C. The mechanical behavior of TRCs with MCF and EP carbon fabrics was characterized through direct tensile tests at room temperature and after being submitted to a thermal regime. The TRC with MCF fabrics presented strain-hardening behavior with a multiple-cracking pattern. The heating up to 300 C did not significantly affect the mechanical performance of the TRC with C-MCF fabric. A structural application analysis of these composites was also performed. For this, RC beams were externally strengthened with MCF- and EP-carbon fabrics TRCs. All TRC strengthening was able to increase the RC beam load capacity. Furthermore, the TRC-strengthened beams presented a multiple-cracking pattern with very fine cracks. In general, the outcome of this study demonstrated that MCF fabrics can be used as an alternative reinforcement in textile reinforced concretes, mainly in situations in which elevated temperatures are expected. With adequate substrate preparation, the MCF-TRC system can also be successfully implemented as a strengthening material for RC beams.
