Concrete patch repair materialUnsaturated polyester resinPatch repair materials made from unsaturated polyester resin (UPR)-mortar have been investigated to determine their bond strength characteristic by slant shear test method. The relative mechanical properties of UPR-mortar and substrate concrete for ...
The results from the cyclic tests indicated a 50 percent fatigue strength of the repaired samples both for the slant shear and the MMOR bond tests. The tests have demonstrated that the laboratory-prepared ordinary portland cement concrete (PORCC) repair material compared well with the proprietary ...
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 between concrete and polyester composites reinforced by silica-based materials of different sizes was investigated. Waste marble dust/silica fume parti...
The slant shear test method, ASTM C882, is widely employed test procedure to determine the bond strength of repair materials for selection of repair material for durable concrete repair. In this test procedure, the repair material is bonded to a substrate mortar specimen on a slant elliptical pl...
The bond strength of concrete materials is high, can not afford to package or layered; 翻译结果2复制译文编辑译文朗读译文返回顶部 The bonding intensity to the concrete material is high, do not get up to wrap up or divide layer; 翻译结果3复制译文编辑译文朗读译文返回顶部 ...
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]...
and foreign experiments,authors proposed that when the thin-walled concrete damaged,the sample was destoryed.Base on this principle,a semiemprical theory formula was deduced using elastic mechanics and material mechanics methods.Analytical results show that bond strength of concrete-filled square steel ...
The James Bond Tester™ MK III or pull off adhesion test measures the bond strength or tensile strength of concrete, asphalt, tile, concrete repair, or other overlay material by the direct tension or pull off method. By pulling a 25mm steel disk attached to the material under the unit can...
the slip between the CFRP and concrete and the cracking type were studied in detail.From the experimental study,it could be found that the influences on bond strength of binder strength,slot size and carbon fiber reinforced surface treatment technology were significant,but the curing time was ...
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
