Bond strength

Asphalt concrete pavement often appears damaged such as rutting, fatigue crack, potholes, etc. at high air temperature, heavy rain in long time, or at locations with high traffic, large horizontal force, and poor-quality construction sites. T This paper presents an evaluation of shear bond strength of double-layer asphalt samples fabricated by shear test device with normal pressure.

This study shows that the stirrups corrosion should receive more attention in the serviceability limit state due to its considerable effect on flexural behavior. Based on a parametric study, it shows that the effect of the crosssection loss of tension reinforcements on the load-carrying capacity of the corroded beam is more significant than the bond strength reduction.

This paper addresses the strength and deformation capacity of slender columns retrofitted by externally bonded Carbon Fiber-Reinforced Polymers (CFRP) subjected to seismic loading. The behaviour of RC columns depending on the CFRP confinement (carbon CFRP jacket) and on flexural reinforcement (carbon plates) was analysed by a nonlinear finite element method based on multilayer shell element and multifiber beams with plasticity and damage models.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

Portland cement concrete (PCC) / asphalt concrete (AC) bonded components are seen in both conventional pavement structures as well as overlays. Due to the environmental and traffic loads, cracks occur at the interface of the PCC and AC layers and finally, may propagate through the interface or one of the layers.

Two chemical treatments were applied to jute fibers to create a better bonding of fiber to resin in natural composite materials. The jute fibers have been treated with hydroxide potassium (KOH) and a bleaching agent, canxi hypochlorite (Ca(OCl)2.4H2O), in varying periods. Characterization techniques such as FT-IR, SEM were used to evaluate the effect of chemical treatments on fiber structure. After treatment the surface topography of jute was clean and microfibrils were revealed, these lead to an enhancement in mechanical properties and interfacial strength between jute fiber and PP.

The solutionmolecular andelectronic structuresof theactive site in the extremelyO2-avidhemoglobin fromthe trematode Paramphistomum epiclitumhave been investigated by 1 H NMR on the cyanomet form in order to elucidate the distal hydrogen-bonding to a ligated H-bond acceptor ligand. Comparison of the strengths of dipolar interactions in solution with the alternate crystal structures of methemo-globin establish that the solution structure of wild-type Hb more closely resembles the crystal structure of the recom-binant wild-type than the true wild-type met-hemoglobin....

Drug-Receptor Interaction partial charges. When a hydrogen atom bearing a partial positive charge bridges two atoms bearing a partial negative charge, a hydrogen bond is created. A van der Waals’ bond (B) is formed between apolar molecular groups that have come into close proximity. Spontaneous transient distortion of electron clouds (momentary faint dipole, !!) may induce an opposite dipole in the neighboring molecule. The van der Waals’ bond, therefore, is a form of electrostatic attraction, albeit of very low strength (inversely proportional to the seventh power of the distance).
