Study on the bonding performance between reactive powder concrete and steel bar
نویسندگان
چکیده
The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists three parts: mechanical bite produced by occlusion reinforcing rib RPC; cementing chemical reaction component surface material reinforcement; Friction surrounding RPC. ultrahigh strength various cementitious materials make Bonding rebar significantly normal This can provide reference for anchorage design structure.

A Study on the Bond Strength between High Performance Concrete and Reinforcing Bar
As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...
