Abstract
In response to the poor anchorage performance and durability of organic reinforcing adhesives,this paper aims to explore the safety and reliability of Ultra-High Performance Concrete(UHPC)as an inorganic reinforcing material.By using UHPC as the reinforcing material,tests on the basic anchorage performance of single rebar and the anchorage performance of rebar groups were conducted.The results show that UHPC,as a bonding and anchoring material,exhibits excellent bonding and anchorage effects.When the diameter of the rebar is consistent,the anchorage performance of the rebar to UHPC increases with the length of anchorage,resulting in a gradual increase in ultimate load and a gradual decrease in ultimate bond stress.UHPC,as a reinforcing material,meets the anchorage requirements for rebar when the anchorage length is greater than 10d.Under different conditions of steel fiber content,rebar diameter,depth of the reinforcing hole,and diameter of the hole,the failure mode is consistently rebar fracture.The findings of this study can provide a reference for the engineering application of UHPC as an inorganic reinforcing material.关键词
