[1062] Evaluation of pull-out behavior of Textile Reinforced Concrete
キーワード：bond behavior、pull-out test、Textile reinforced concrete、TRC
The extensive utilization of Textile Reinforced Concrete (TRC) in modern days demands to standardize the test methods for determining mechanical properties, particularly bond behavior between textile reinforcement and mortar. Pull-out test is a typical method utilized to obtain bond behavior. The aim of this study is to propose a pull-out test for evaluating the bond behavior of textile reinforcement and cement matrix in TRC. Tests with different embedded lengths were conducted in order to characterize failure modes of textile roving as well as obtain a representative trend of pull-out behavior. The proposed test method gave stable load - displacement relationship, and it seems the proposed test method can provide reasonable and reliable results on the bond characteristic in TRC.
