ALKALI-AGGREGATE REACTION IN NORTHERN FRANCE: A REVIEW

A statistical survey was conducted on 140 bridges located in the northern part of France (Lille, Reims and Paris). This survey indicates that 5% of the studied bridges present important degradation signs likely related to AAR; 24% of the bridges show evident signs of AAR having caused up to now only minor damages; 57% of the bridges show little degradation signs; and 14% of the bridges show no degradations. This study enlightens the close relationship existing between the used aggregates (siliceous aggregates or metamorphic limestones aggregates containing pyrite) and the observed deteriorations. The chemical characteristics of the AAR gels are presented. The negative correlation existing between the concrete compressive strength and the gel alkali contents argue for a more expansive nature of the alkali enriched gels.
