| Abstract: | In order to promote the research and application of reactive powder concrete(RPC).Launches some investigation on raw materials and their contents selection based on an under-construction railway express located in South of China where RPC member is in demand.The results show that by routine modeling and steam curing or standard curing,concrete with compressive strength of higher than 130 MPa is obtainable under the premise of appropriately mixing coarse and fine quartz sand as well as incorporation of miner... |
