Experimental Study on the Bonding Performance between Fiber-Belt-Bar and Concrete

Fiber materials have advantages such as light weight and high strength, corrosion resistance, fatigue easy processing production, they are widely applied in the repair renovation of concrete structures. To promote construction convenience fiber materials, raw yarn is continuously braided to form fiber-belt-bars. Based on existing research, performance bonding between fiber-belt-bars a interface was investigated, pull-out tests were performed systematically investigate effects fiber-belt-bar cross-sectional size, anchorage length, type performance. The experimental results show that bond strength reduces with an increase decrease effect not obvious. On this basis, formula for calculating average proposed. Experiments calculations determined size 12 mm × 3 10–30% higher than 20 same length. Finally, minimum length proposed provide valuable reference use projects.
