Experimental Study on the Pull-Out Behavior of Fasteners in Carbon Textile Reinforced Concrete Plates

Carbon reinforced concrete (CRC) offers environmental benefits and enables the construction of slender, thin-walled, and geometrically flexible structural elements. Nevertheless, extra caution is essential for thin components when requiring the incorporation of fasteners through precast or post-cast methods. The behavior of fasteners in thin CRC elements is of most importance, as it represents a pioneer exploration into the future of construction. However, the behavior of fasteners in CRC differs from that in conventional steel-reinforced concrete (RC) components due to the reduced thickness. This paper investigates the maximum strength and failure behavior of thin concrete plates with cast-in-place fasteners, examining both plain and textile-reinforced concrete. The overall cracking behavior of plain concrete plates was decisively influenced by the occurrence of splitting cracks. The introduction of textile reinforcement shows a significantly higher ultimate strength of the concrete plate and shifts the failure mode to pullout failure than splitting failure in plain concrete components.
