Abstract:Three test methods have been applied in Norway for 20 years to classify the alkali reactivity of concrete aggregates. The Norwegian 38°C concrete prism test was in 1996 also specified in the Norwegian guidelines for performance testing of concrete mixes and/or binders. Since then, more than 160 such performance tests have been carried out in Norway. The main objective with this paper is to discuss the experiences gained from these tests. The Norwegian concrete industry has successfully used the performance test as a flexible tool to be able to utilize alkali reactive aggregates.
