1.2—Definitions
corrosion—destruction of metal by chemical, electrochemical,
or electrolytic reaction within its environment.
dampproofing—treatment of concrete or mortar to retard
the passage or absorption of water, or water vapor, either by
application of a suitable admixture or treated cement, or by
use of preformed film, such as polyethylene sheets, placed
on grade before placing a slab.
excavation—steps taken to remove deteriorated concrete,
sound concrete, or both, designated for removal.
nonstructural repair—a repair that addresses local
deterioration and is not intended to affect the structural capacity
of a member.protection—the procedure of shielding the concrete structure
from environmental and other damage for the purpose of
preserving the structure or prolonging its useful life.
repair—to replace or correct deteriorated, damaged, or
faulty materials, components, or elements of a structure.
repair systems—the combination of materials and
techniques used in the repair of a structure.
strengthening—the process of restoring the capacity of
damaged components of structural concrete to its original
design capacity, or increasing the strength of structural
concrete.
structural repair—a repair that re-establishes or
enhances the structural capacity of a member.
surface preparation—steps taken after removal of
deteriorated concrete, including conditioning of the surface of
substrate at bond line and the cleaning of existing reinforcing
steel.
waterproofing—prevention of the passage of water, in
liquid form, under hydrostatic pressure.
