ALKALI AGGREGATE REACTION IN ICELAND – NEW TEST METHODS
In this project, four different test methods for Alkali Aggregate Reactions were examined. For each method, eight different Icelandic aggregates were tested and in addition one of the eight aggregates was tested in all four methods with nine different cement- and pozzolanas combinations. The results...
