Textile-reinforced concrete has great potential for use in lightweight, thin-walled structural components. Since such elements participate directly in load transmission in the structural framework, satisfactory fire resistance is often desirable. Experience until now, however, has been limited with respect to the behavior of textile concrete elements subjected to fire. In this investigation, four fire tests have been performed on textile-reinforced concrete sections (I-profiles), in which one side of the sections was exposed to fire. The textiles tested were AR glass, carbon, and carbon coated with styrene butadiene. These experiments demonstrated that the load-bearing behavior of textile-reinforced structural components in fire greatly depends on the textile used, their bond to the concrete, and the behavior of the concrete under high temperatures.
