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.

Concerning the same groups in different storage times, most of the groups maintained their bond strengths (p[greater than or equal to]0.05), except for G2 (ASB), where a significant decrease in bond strength was observed after 3 (p=0.000) and 6 months (p=0.037) storage times compared to the baseline; and for G5 (SBU+CHX), where a different pattern was observed and bond strength results from 3 and 6 months were significantly higher compared to 72 h (p[less than or equal to]0.05).
