Steel–concrete bond strength of lightweight self-consolidating concrete
Materials and Structures, 2008The bond behavior of lightweight self-consolidating concrete (LWSCC) must be understood in order to use this type of high performance concrete in structural members. The objective of this research program is to assess the bond behavior of reinforcing steel bars embedded in LWSCC members. Three different classes of LWSCC mixtures were developed with two

Analysis of the Loss of Steel-Concrete Bond Due to the Migration of Ions
ECS Meeting Abstracts, 2014ABSTRACT In this work, the degradation of bond between steel and concrete under cathodic protection conditions (-1000mV≤ E ≤ -850mV vs. Ag/AgCl) and cathodic overprotection ((E < -1000 mV vs Ag/AgCl) by impressed current applied in two mixtures submerged in a solution of 3.5% wt. NaCl was evaluated;

Steel concrete bond model for the simulation of industrial structures
2011This paper presents a new finite element approach to model the steel-concrete bond effects. This model proposes to relate steel, represented by truss elements, with the surrounding concrete in the case where the two meshes are not necessary coincident. The theoretical formulation is described and the model is applied on a 3D simulation of a reinforced ...

Long-Term Performance of Epoxy Bonded Steel-Concrete Joints
1986The technique of strengthening reinforced concrete structures by means of epoxy bonded steel plates becomes more and more familiar in renovation industry. It shows to be a reliable and fast repair method, not only under normal laboratory conditions but also under atmospheric and sustained loading conditions.

Influence of rebars in HI-Bond Steel-Concrete composite slabs
2022Steel–concrete composite slabs represent an efficient floor solution combining the key performance of two different materials: the concrete, able to resist to compressive stresses and the steel of the hi-bond thin profiled sheeting, supporting tensile forces.

Steel–concrete bond behaviour of self-compacting concrete with recycled aggregates
Magazine of Concrete Research, 2016Tests were conducted to examine the bond of reinforcement in self-compacting concrete (SCC) produced using recycled coarse aggregate (RCA). The study considered one natural coarse aggregate, two sources of RCA (concrete tested in the laboratory and concrete from demolished old structures), two types of RCA (pre-treated and untreated), three RCA ...

Finite Element Modelling of Steel/Concrete Bond for Corroded Reinforcement
2015Reinforcement corrosion is the most common deterioration problem observed in reinforced concrete (RC) structures located at coastal or cold regions. The corrosion process can impact the performance of these structures by inducing damage on the bonding action between concrete and steel, either by the splitting of the concrete cover due to the volumetric
