Abstract

Abstract

Corrosion of steel is an important factor affecting the bonding properties of steel and concrete. In order to explore the bonding properties of reinforced concrete with rebar HRB600 under stable corrosion rates, the pull-out tests were carried out on 36 anchorage specimens of bond between rebar HRB600 and high-strength concrete under stable corrosion rates, and the characteristics of the bonding strength and its influencing factors were analyzed. Finally, the variable laws of influencing factors on the bonding properties were calculated by test data under the relatively stable corrosion rates, and the calculation formula of the ultimate bonding strength was fitted.
- HRB600,
- high-strength concrete,
- stable corrosion,
