Abstract:
In Japan, sea sand is used frequently as fine aggregate for concrete. The mining of sea sand has been more difficult year by year for environmental reasons. This would be a serious problem in manufacturing concrete. The amount of fly ash has been increasing gradually in Japan, therefore the utilization of fly ash as the substitution of fine aggregate has a significant advantage. In this study, bending fatigue test of roller compacted concrete was carried out, in which all fine aggregate was replaced with fly ash. The obtained S-N curve was compared with that of normal concrete and general roller compacted concrete. Scatter of fatigue strength was also determined.
