ISO 5091-2:2023

This document specifies structural intervention of existing concrete structures using cementitious materials design and execution principles, and strategies for defects and on-going deterioration including, but not limited to:

a)       mechanical actions, e.g. fatigue, impact, overloading, movement caused by settlement, blast, vibration, and seismic actions;

b)       chemical and biological actions from environments, e.g. sulfate attack, alkali-aggregate reaction;

c)        physical actions, e.g. freeze–thaw, thermal cracking, moisture movement, salt crystallization, fire, and erosion;

d)       reinforcement corrosion;

e)       original construction defects that remained unaddressed from the time of construction.
