精品 摘要 随着我国改革开放和现在化进程的加快，我国的建设规模正日益增大，如何保证建筑工程质量的同时也能使工程能长久的安全使用下去，日益受到各级政府和社会各界的广泛关注。在众多的土木建筑工程建设中，混凝土的应用面之广，使用次数之多是很少见的。尤其中近年来，一种较新的混凝土技术正在快速发展并且运用到许多实际工程项目中，那就是高性能混凝土。 高性能混凝土（Hinh Performance Concrete HPC）由于具有高耐久性、高工作性、高度和高体积稳定性，被认为是目前全世界性能最为全面的混凝土，至今已在不少重要工程中被采用，特别是在桥梁。高层建筑、海港建筑等工程。 本文主要介绍了高性能混凝土发展的历史背景及目前国内外的研究现状，阐明了高性能混凝土的特性，列举了高性能混凝土在国内外研究应用的重要成果，并对其发展趋势作出展望。随着我国建筑向高层化、大型化、现代化的发展，HPC必将成为新世纪的重要建筑工程材料。 关键词：高性能混凝土：耐久性：体积稳定性 ABSTRACT With Chinas reform and opening up and now in the process of speeding up, the construction scale is enlarging, how to ensure the quality of construction projects also can make long-term safety engineering can use down by governments at all levels, increasingly wide attention and all circles of the society. In many of the construction of civil engineering and construction of concrete application, widely, use frequency is very rare. Especially in recent years, a relatively new concrete technology is rapidly developed and applied to many practical engineering projects, that is high performance concrete. High Performance Concrete (HPC) because Hinh Concrete Performance with high durability, high workability, height and high volume stability, thought to be the most comprehensive Performance of Concrete around the world in many important, has so far been adopted in engineering, especially in the bridge. High-rise buildings, harbor construction projects. This paper mainly introduces the development of high performance concrete historical background and the research situation at home and abroad, expounds the characteristics of high performance concrete, lists the domestic and foreign research and application of the high performance concrete at the important achievements, and prospected its development trend. Along with our country building to top change, the development of modernized largescale, will become the new century, HPC important building engineering materials. Keywords: high performance concrete: durability: volume stabil
