The needs of societies must be met by the evolution and innovation of new products to meet them adequately, taking into account the economic, social and environmental aspects, and should follow a continuous flow of development. In civil engineering, the search for new materials is fundamental. In this context, textile concrete arises, a material where steel rebar is replaced by a composite consisting of bidirectional continuous fibers, involved in a polymeric material, distributed in mesh shapes, of the following types: glass, carbon, and aramid. This material is an advance for the structuring of reinforced concrete, due to the total replacement of the steel reinforcement, thus not existing the probability of reinforcement corrosion - a major current problem - in addition to providing a reduction of the sessions of the concrete parts and the weight of the same, since there is no need for a cover layer. This paper is a literature review on the topic of textile concrete, where an analysis of scientific texts published as books, articles, theses, dissertations, between the years 2016-2022 was performed, aiming to characterize this new material. Although it is a new material and is under development, it has shown promise in the market, since, in addition to non-corrosive and non-magnetic components, it has shown satisfactory performance in relation to tensile strength, durability against the action of aggressive agents such as chloride ions, carbonation and resistance to high temperatures - for certain conditions of reinforcement - becoming a new alternative to problems currently faced in the reinforced concrete structure.
