In order to determine effects cf part replacement of cement by pozzolans and of entrainment of air on the bond to steel strength of concrete with plain and deformed bars, series of laboratory studies were carried out on concretes of different strengths using air-entraining and pozzolanic ...
bond strength of concrete-filled square steel tube specimen is more affected by width-thickness ratio,and is less affected by the slenderness.The results of formula match well with those of experiments,which provide a new way to calculate bond strength of concrete-filled square steel tube columns...
Test results indicate that significant bond strength exists to resist the pull out of a concrete core from a steel pipe in a tension joint. This is true even after 1100 high load cycles and after a year of exposure to severe weather. Measurements of strain distribution and slip were made on...
Degradation of bond strength due to corrosion of steel strands is of great importance for serviceability of prestressed concrete structures. An analytical model is proposed to demonstrate the effect of corrosion of steel strand on reduction of bond stren
According to the pullout test of two kinds of corroded steel bars, the bond behavior of corroded plain and deformed bars was discussed then. On the basis of the test data, the formulas of bond strength of corroded steel bars and concrete were developed. This paper also gave the relationship...

Experimental Investigation of the Influence of the Bond Conditions on the Shear Bond Strength between Steel and Self-Compacting Concrete Using Push-Out Tests Steel-concrete joints are often provided with welded shear studs. However, stress concentrations are induced in the structure due to the welding...
Effect of corrosion on the bond between concrete and steel rebar The effect of corrosion on the bond between concrete and steel rebar was studied by measuring both bond strength and contact electrical resistivity. Corros... X Fu,DDL Chung - 《Cement & Concrete Research》 被引量: 174发表: ...
, the maximum bond force per unit length depends primarily on the bar diameter, the amount of enclosure provided by transverse reinforcement (hoops, ties, or stirrups) placed around the bar, or confinement provided by external concrete(concrete cover), as well as the concrete tensile strength....
aBond strength between fiber and concrete is another important consideration. Steel has very high tensile strength, but steel fibers have low bond strength with concrete or mortar. 接合强度在纤维和混凝土之间是另一重要考虑。 钢有非常高强度力量,但钢纤维有低接合强度与混凝土或灰浆。[translate]...
