ALKALI-AGGREGATE REACTION - MINIMISING THE RISK OF ALKALI-SILICA REACTION. GUIDANCE NOTES

These notes give the basic essential information on the circumstances under which damage due to alkali-silica reaction could occur and on ways to avoid or minimise such damage in new concrete construction. The notes apply to materials, conditions and practice in the United Kingdom. Structural elements which have been known to suffer from alkali-silica reaction include foundations, columns, bridge beams, parapets, retaining walls and structures subject to high humidity such as multi-storey car parks. Notes are included on: limiting the amount of reactive alkali available, assessment of aggregates, alkali migration, effect of precautions on concrete properties. The chemistry of the alkali-silica reaction is described and a worked example to illustrate the recommendations is included. The location of reported cases of alkali-silica reaction in the United Kingdom is shown. (TRRL)
