Abstract:
The main advantage of textiles as reinforcements in cement-based composites is in the enhancement of mechanical behavior. Textile-reinforced concrete (TRC) has emerged as a novel composite with various potential applications in non-structural and, more recently, structural building materials, including thin and slender elements, repair, and strengthening of existing structural members. The wide variety of textile production methods allows great flexibility in textile design, which enables controlling of textile geometry, yarn geometry, and orientation of yarns in various directions. This diversity is advantageous in the development of cement-based composites and allows engineering of the performance of the final products for the desired requirements. Recognizing the increasing research interest in thin fiber-reinforced cement-based composites using fabrics and hybrid systems (fabrics + chopped fibers) and their emerging industrial applications in the last years, there has been a close communication and collaboration between ACI Committee 549, Thin Reinforced Cementitious Products and Ferrocement, and RILEM TC 201, Textile Reinforced Concrete (TRC), in the area of TRC. Following two two-part technical sessions, held at the 2005 ACI conventions in New York and Kansas City, ACI Committee 549 sponsored the technical session “Design and Applications of Textile Reinforced Concrete” at the ACI Fall 2007 Convention in Puerto Rico. Seven papers were presented by invited international experts from Germany and co-authored by members of RILEM TC 201. This Special Publication (SP) contains seven papers that provide insight into the state-of-the-art design and application of TRC. The topics of the papers cover the following: materials aspects related to serviceability; strength and damage accumulation; TRC for flexural strengthening of reinforced concrete structures – structural behavior, design model, and application for a concrete shell; use of TRC as a subsequently applied waterproof structure; application of TRC for lightweight structures; and sandwich panels with thin-walled TRC facings for structural exterior walls and nonstructural façades. The papers included in this publication have been peer reviewed by international experts in the field according to the guidelines established by the American Concrete Institute. The future of thin fiber and textile-reinforced cementitious systems depends on their ability to compete with existing solutions and to identify new applications. Efforts are required in the areas of process, design, and implementation in industrial and full-scale applications of TRC. On behalf of ACI Committee 549, the editor would like to thank all the authors for their contributions and the reviewers for their assistance and valuable suggestions and comments.
