The ASR suppression effect of fly ash, silica fume and the combination of them was evaluated by both concrete prism test and mortar bar test. Concrete prism bars were made based on RILEM AAR-3, meanwhile mortar prism bars were made according to JIS A 1146. Both prism specimens were stored in 40oC 100% R.H. controlled room. Two aggregates were used in this experiment; one was classified as alkali silica reactive (andesite) and the other was classified as non-reactive (limestone). The present study investigated the combination of fly ash (FA) and silica fume (SF) in order to reduce expansion due to ASR, and some concrete and mortar mixtures have been made in pessimum proportion. The results indicated that the combination of FA and SF showed smaller expansion compared to FA.
