%X This investigation is focused on bending experiment of some prismatic perlite lightweight concrete. In these samples, textile waste fibers are confined with textile mesh glass fiber and embedded in the central part of cubic lightweight concrete specimens. Bending experiments revealed that lightweight concrete panels with a core of textile waste fiber have less density than water and high energy absorption and ductility. Furthermore, these composite panels by having appropriate thermal insulation characteristics could be used for partitioning in the buildings. 1. Introduction In advanced industrialized countries, the utilization of fibers in concrete began in the early 1960s [1]. The type and form of fibers and also the construction of fiber-reinforced concrete (FRC) have improved significantly during the past five decades, and their employment have been on the rise [2, 3]. Improving the mechanical properties of concrete using the random distribution of fibers in it has been the topic of interest of numerous research studies [3¨C7]. Between 1994 and 2011, Wang et al. carried out several research efforts on adding carpet waste fibers to concrete and soil. In this research, the old carpets were transformed into fibers. These fibers were not necessarily of the same size and were actually used in many different shapes and sizes in concrete and soil. After compressive and bending experiments, the results showed that the usage of waste fibers had significant effects on the resistance of failure, stiffness, and ductility of concrete. The usage of this cheap waste in concrete has also increased the durability of concrete [8¨C10]. In recent years, dos Reis et al. examined the mechanical properties of FRC with textile waste fibers. In this research, the textile wastes of Nova Friburgo industry, located in Rio de Janeiro in Brazil, were used. The general purposes of this research were exploring the mechanical properties of reinforced polymer concrete and best use of textile waste fibers considering increased production of this kind of waste in Brazil. On an overall result, it was stated that the cutting waste textile fibers mixed with polymer concrete produce a unique composite material which had lower flexural and compressive characteristics as compared to unreinforced polymer concrete. Using these textile wastes in concrete lead to a smoother failure, unlike brittleness failure behavior of unreinforced polymer concrete. Furthermore, the usage of textile waste may solve the problems like environmental pollution and provision of an alternative material for the
