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.

For samples modified by the silane coupling agent, higher average values of bond strengths than those without the modification throughout the entire exposure timeline are evident for the 0-, 4-, and 12-week exposure although the difference at 12 weeks is less than one standard deviation and thus may not be significant.
