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 deocrative concrete'. The occurrence of damage as a result of alkali-aggregate reaction has now been Identified in 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 of alkali-aggregate reaction. The paper descriptionbes the effects of alkali-aggregate reaction on exposed reinforced concrete structures and some of the techniquel that have been developed to effect repairs to structures in the Witwatersrand area.
