Abstract: Rock-filled concrete (RFC), which is formed by filling specific self-compacting concrete into rockfills, is a type of dense concrete, not just environmental friendly but of easy construction, low-heat hydration, and low cost. In China, RFC is widely used in mass concrete projects in hydraulic and hydropower engineering, highway and railway engineering, harbor engineering, etc. Up to the present, comprehensive experimental studies and extensive numerical analysis on its performance have been carried out. This article presents a summary and analysis of its thermal property, mechanical property, long-term performance and durability, and suggests some issues for further studies.
