摘 要 自我国改革开放以来，国家迅速的发展，一步步的走向现代化，与此同时我国的建设规模也在不断的壮大，那么如何保证建筑工程质量以及使工程能长久的安全使用下去，必将是各级政府和社会各界广泛关注的焦点。大量的土木工程建设当中，混凝土的应用面是非常之广，使用次数很多。特别是近几年来，一种新兴的混凝土技术出现并运用到很多工程顼目中而且迅速的发展着，那就是高性能混凝土。 高性能混凝土(High Performance Concrete，HPC) 具用许多优点，如具有高高耐久性、高工作性、高强度和高体积稳定性等，正因为这些优良的特性，被认为是目前全世界性能最为全面的混凝土，有许多的重要工程开始采用HPC，尤其是在海港建筑、高层建筑、桥梁等工程。 本文主要围绕高性能混凝土的发展历史背景和目前国内外的研究现状展开研究的，文章主要介绍了什么是HPC、HPC所具有的特性，枚举了一些有关HPC在国内外研究领域应用中的主要成就，并展望了HPC的未来发展趋势。近几年来，我国建筑逐渐向大型化、高层化、现代化迅速迈进，以此来看，新世纪的重要建筑工程材料必将是HPC。 关键词 高性能混凝土；定义；特性；发展趋势 Abstract Since Chinas reform and opening up, the rapid development of the country , a step toward modernization , while the size of the building is constantly growing, so how to ensure the quality of construction so that the project can be a long and safe use of it, is bound to each levels of government and community-wide focus. Among a large number of civil engineering construction , concrete application surface is very wide, use many times . Especially in recent years , an emerging concrete technologies emerge and applied to many engineering Xu heads and rapidly developing , and that is high performance concrete . High Performance Concrete (High Performance Concrete, HPC) with with many advantages, such as having a high durability , high resistance, high strength and high dimensional stability , etc. , because these excellent features , is considered the worlds currently most performance comprehensive concrete, there are many important projects began to use HPC, dragon which is in the harbor building , high-rise buildings, bridges and other projects. This paper mainly focus on the historical background of the development of high performance concrete research status at home and abroad and the commencement of the study , the article describes what is HPC, HPC has the characteristics enumerated some of the HPC research at home and abroad of the main areas of application achievements and prospects for the future development trend of HPC .
