Description

This guide describes specific types of concrete deterioration. Each chapter contains a discussion of the mechanisms involved and the recommended requirements for individual components of concrete, quality considerations for concrete mixtures, construction procedures, and influences of the exposure environment, which are all important considerations to ensure concrete durability.

This guide was developed for conventional concrete but is generally applicable to specialty concretes; however, specialty concretes, such as roller-compacted or pervious concrete, may have unique durability-related issues that deserve further attention that are not addressed herein. Readers should consult other ACI documents for more detailed information on special concretes of interest.

Keywords: abrasion resistance; acid attack; admixture; aggregate; air entrainment; alkali-aggregate reaction; calcium chloride; carbonation; cement paste; corrosion; curing; deicer; deterioration; durability; fly ash; freezing and thawing; mixture proportion; petrography; pozzolan; reinforced concrete; salt scaling; sea water exposure; silica fume; skid resistance; spalling; strength; sulfate attack; supplementary cementitious materials; temperature; watercementitious material ratio.
