oa Civil Engineer in South Africa - The repair of reinforced concrete structures affected by alkali-aggregate reaction

 

Abstract

As late as 1976 Fulton wrote : 'in South Africa the only known cases (of alkali-aggregate reaction damage to concrete) have arisen when glass has been used as an aggregate or in the form of insets in decorative concrete'.


The occurrence of damage as a result of alkali-aggregate reaction has now been identified in the the Western and Eastern Cape and also the Witwatersrand area. Very little is known of how to repair structures that have deteriorated as a result alkali-aggregate reaction.
The paper describes the effects of alkali-aggregate reaction on exposed reinforced concrete structures and some of the techniques that have been developed to effect repairs to structures in the Witwatersrand area.
