Abstract:This paper gives an introduction to the development of high strength concrete of Chinese railway for 50 years. The development experience can be divided into three stages .In the first stage,C40-55 dry and low plastic high strength concrete was made from common HSC and plastics doped compound agent (dehumidifying agent) HSC by adopting the techniques of bench vibration, side form vibration and bottom die vibration, for massive production of pre -stressed concrete tie , tube pile , post of catenary and bridge. In the second stage , the plastic HSC was made with NSF high efficient dehumidifying agent. The systematic experiments were done for ‘physical mechanics and structure performance of NSF-HSC according to the features of railway traffic , such as high speed,heavy haul,dynamic loading and safety. In the third stage, the ASF high efficient and PCE high efficient dehumidifying agents were produced and applied. This paper concludes that the PCE high efficient dehumidifying agent call meet the requirements of railway engineering and. is an ideal agent for high strength and high performance concrete for railway.
