Abstract

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.
