Concrete’s durability is the ability to resist deterioration over time, and
maintain its engineered properties like strength, form and aesthetics. Durable concrete
is more sustainable and more economical, and a variety of techniques can be
used on hardened concrete to evaluate its durability. The techniques outlined are focused
on: freeze and thaw and scaling, alkali-silicate reactivity, petrographic examination,
abrasion and erosion, chloride content determination, steel reinforcement
corrosion potential, RCP, and fluid penetration resistance.
Keywords: Absorption, alkali silicate reactivity (ASR), freeze and thaw, permeability tests, rapid chloride permeability test
(RCPT), steel reinforcement corrosion, sulfate attack.
