| Because the roving of textile can be oriented in line with the occurring stresses. Textile Reinforced Concrete (TRC, for short) could make a high effectiveness of the reinforcement for conctete. TRC have many advantages such as superior bearing capacity, fine toughness, antimagnetization, lightweight and easy performance. And Ultra High toughness Cementitious Composite(UHTCC,for short) shows prominent toughness and ultra shock resistance and the ability of crack controlling. After combining TRC and UHTCC, the new matrial not only obtains theirselves advantages, but also could get more superior abilities of crack resisting and controlling. So the durability and service life of concrete structure would be enhanced to a large degree. But Whether they have a better bonding property between textile and UHTCC will guarantee their coordinate-working and make good use of their advantages. According to the reason above, a series of tests and analytical work about textile and UHTCC have been completed in the paper.1. Obtaining some mechanical properties of textiles which is used in the paper through pull-out tests.2. Studying the influences of the surface treatment of textile, volume content of PVA fiber and the thickness of covering layer on flexural properties on the basis of four-point bending tests in this paper.3. On the base of pull-out tests investigating the influences of surface treatment of textile, initial bond length of textile, volume content of PVA fiber and weft fibers. on bonding property. And analyzing the result of the tests to give some suggestions to improve bonding property between textile and UHTCC.4. Making use of triple linear model to analyze pull-out tests above. It could help understanding the characters of sticky point and be essential for structural calculation later.
