The performance of such overlays relates mainly to the concrete-to-concrete bond. The regulations of the German annex of Eurocode 2 for 'shear at the interface between concrete cast at different times' eliminates the usage of self-consolidating concrete (SCC). In this paper, the properties of ...
What is an acceptable value to use for strength level bond stress between 4 ksi grout and smooth concrete? I am designing floor framing comprised of...
These forms are oiled to avoid their adhesion with the hardened concrete material. The reinforced steel bars may be polluted with the oil when they placed over or inside the forms. This pollution may affect the bond between the steel bars used and concrete and consequently the strength of ...
The bond strength of polymer composite to the concrete surface is a critical aspect of bridge and parking structures. In this study, the bond strength betw
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...
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...
In this paper, the prediction of flexural strength was investigated using machine learning methods for concrete containing supplementary cementitious materials such as silica fume. First, based on a database of suitable characteristic parameters, the fle
The effects of curing time,binder strength,slot size and surface treatment on the bond strength were further studied.Pullout tests of 36 specimens were conducted to study the bond strength of the CFRP rods,and then four different bond materials were compared.During the experiment process,the failu...
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]...
