摘　　要：超高强高性能混凝土因其优异性能而被逐步应用于当今工程建设中。然而,有关超高强高性能混凝土配合比设计理论、制备工艺和长期时变性能等方面研究还不深入,从而限制了超高强高性能混凝土的工程应用。总结了国内外有关超高强高性能混凝土配合比设计、生产制备和长期性能等方面研究成果,指出了现有超高强高性能混凝土研究存在问题和不足,为超高强高性能混凝土的配合比设计、制备与应用等提供理论指导和技术支撑。Due to excellent performance,the super high strength high performance concrete has been gradually used in the construction field.However,the widespread use of super high strength high performance concrete is still limited,which is on account of the inadequate research on concrete mix proportion design theory,preparation process,long-term properties and time-dependent performance.It summarizes the achievements of mix proportion design,preparation and performance of super high strength high performance concrete,and concludes the existing problems and shortcomings of the existing research on super high strength high performance concrete.The results can provide theoretical guidance and technical support for the mix proportion design,preparation and application of super high strength high performance concrete.
