Over 20 years have passed after beginning of RCD research, and over 15 RCD projects have built or are under construction. On the other side, RCC has been applied to many dams and other projects. Outlines of these two constrution methods have pesented in ICOLD Bulletin 75 “Roller Compacted Concrete for Gravity Dams”- State of the Art. However, technical manuals or other detailed technical reports have been published in only Japan and United States.
A way of thinking about design proportion of extremly dry concrete and the difference between RCD method and RCC method are described in this report. It is expected to contribute to the development of the concrete dam construction.
