bond strength

[′bänd ‚streŋkth]
(chemistry)
The strength with which a chemical bond holds two atoms together; conventionally measured in terms of the amount of energy, in kilocalories per mole, required to break the bond.
(engineering)
The amount of adhesion between bonded surfaces measured in terms of the stress required to separate a layer of material from the base to which it is bonded.

bond strength

1. The resistance to separation of mortar and concrete from reinforcing steel (or other materials) with which it is in contact.
2. All forces that resist separation, such as adhesion, friction due to shrinkage, and longitudinal shear in the concrete engaged by the bar deformations.
3. The applied unit load in tension, compression, flexure, peeling, impact, cleavage, or shear required to break an adhesive assembly, with failure occurring in or near the plane of the bond.

Our work with soy flour has shown that dry and wet adhesive bond strengths for samples made and tested using this ABES method were remarkably insensitive to the type of soy flour used (Frihart and Satori 2012) or to the addition of chaotropic agents, salts, surfactants, and co-solvents to the soy flour (Frihart and Lorenz 2013).

The conventional grouts shrank more, had only modestly higher compressive and bond strengths, cracked earlier, and cost substantially more.
When the bond strengths of the exposed specimens for three groups, which varied with different surface conditions, are compared with each other, it is shown that the average value of the bond strength was higher for the exposed specimens modified by the epoxy-functional silane.
Increasing the application time of primer in a multistep system from 10 to 40 seconds increased the shear bond strengths; also the shear bond strengths increased when the adhesive resin's pre-curing time was lengthened [Nour Eldin et al, 2002].
Shofu's BeautiBond[R] is a seventh generation bonding agent with bond strengths comparible to 4th, 5th and 6th generation materials, according to the manufacturer.
The average values of shear bond strengths were defined as loads at fracture divided by the 4 mm diameter iris areas.
However, further numerical data were generated by subjecting the surviving specimens to the usual tensile pull test and recording the loads to failure, just as was done for the original bond strengths.
FDM 200mc, which replaces the previous Prodigy Plus system, uses new Insight flow-control software and a new material, ABSplus, said to offer better flow and higher tensile, flexural, impact, and bond strengths than standard ABS.
