Abstract:
Icelandic aggregates are often alkali-reactive, notably because of their glass content. Pulverized rhyolite glass was used as a pozzolan until 1979, when an amendment was made to the Icelandic building code to safeguard against AAR damage. This amendment requires sea-dredged aggregates to be washed to a minimum chloride content, and not less than 5 percent silica fume be intermilled with the cement clinker.
