Abstract:The pullout and fourpoint tests of thinwalled plate specimens were carried out to investigate the bonding and overlapping performance of textile in fine grained concrete. The experimental results show that the warp yarns and the surface treatment of the textile have significant influences on the interfacial bond performance between the textile and the fine grained concrete. In addition, for the textile covered with or without sand, with the increase of the initial bond length of carbon fiber yarn, the average interfacial bond strength has a falling trend, and when the initial bond length is longer than 35 mm, it is enough to ensure that carbon fiber yarns can have sufficient bond to the fine grained concrete and can not be pulled out. For the textile covered with fine sand, if the overlapping length of carbon fiber is longer than 60 mm, the requirement for the stress transfer between fiber yarns can be met. At the same overlapping length, the enhancement capacity of the textile using the binding overlapping are better than that of the textile using the sticking overlapping.
