Study on rock-fill concrete dam

A new type of concrete namely rock-fill concrete(RFC) is proposed.The concrete is constructed by pouring the self-compacting concrete into the rock-fill body.Laboratory test results show that by using this technology a dense and high strength concrete structure can be easily constructed.The possible new types of dam based on this technology,namely RFC arch dam/gravity dam,RFC Core Rock-fill dam and RFC Mixing dam,are investigated.
