Concrete

CATEGORIZATION OF DEFECTS

Other type of defects and “Safe Side” categorization

INCLUDES:
▪ Other type of faults and damages on concrete elements and structures
not categorized previously in this document.

CATEGORIZATION / ACTION:
▪ Categorization shall be based on the “best judgment” and consider how
critical is the concrete element for the entire structure and what could the

timeline for a further degradation leading to a failure of the element.
▪ In case of doubt, it is recommended that the inspector categorize the LFF

in a conservative way (higher LFF) and trigger immediate reparation or
Expert Assessment.
▪ Criticality of a member or a part of a member shall be considered. Critical

members are those essential for the structural integrity (ex: columns,
welds in suspended hopper).
▪ Consider the possibility of some members apparently not loaded during
an inspection may be occasionally extremely loaded (example: Effect of
lateral wind load on bracing elements).

Examples:

Alkali-silica reaction
Honeycomb Blistering (chemical damage)

Spaling Carbonation (chemical damage) Efflorescence (water damage)
