Bond strength between stell-concrete and between concretes with different ages in structural rehabilitation

Revista IBRACON de Estruturas e Materiais
In inspections of buildings, it is common to find structures that, well before reaching its useful life longer require repairs and reinforcements. This study examined the bond strength between concrete of different ages and between steel and concrete ...

Bond behavior between steel and solid waste concrete activated by soda residue and carbide slag in concrete-filled steel tubes (CFSTs)

Case Studies in Construction Materials
In recent years, the increasing emphasis on sustainable development in civil engineering has significantly advanced research on solid waste materials. However, the practical application of these materials in structural engineering remains limited.

Experimental and numerical investigations on the bond-slip behavior of the interface between geopolymer concrete and steel tube

Scientific Reports
This study conducts push-out tests on eight geopolymer concrete filled steel tube column specimens with varying design parameters to evaluate the effects of steel tube wall thickness, concrete strength, and the presence of welded longitudinal ribs on the

Modelling the loss of steel-concrete bonds in corroded reinforced concrete beams [PDF]

, 2007
The existing stochastic models for deterioration of reinforced concrete structures is extended by adding modelling of “loss of bond” due to corrosion between the reinforcement bars and the surrounding concrete.

An Experimental Investigation on the Improving the Bond Behavior of Glass Fiber Reinforced Polymer Bars in Concrete

Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ
The bond is considered one of the factors that plays an important role in the behavior of the reinforced concrete structural elements. In recent years, using the glass fiber reinforced polymer (GFRP) as an alternative to steel bars is needed to verify ...

Effect of corrosion on bond between reinforcement and concrete-an experimental study

Discover Civil Engineering
The presence of cracks in concrete structures can lead to corrosion as it exposes the steel reinforcement to environmental factors. When moisture and oxygen reach the steel, corrosion weakens the bond between the steel and the surrounding concrete.
