摘 要 自我国改革开放，我国的建设规模，如何保证建筑工程质量使工程能长久的安全使用下去，各级政府和社会各界广泛关注。的土木工程建设中，混凝土的应用面之广，使用次数。 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 . In recent years, Chinas building gradually to large-scale , high-rise , modern fast forward, this point of view, an important construction materials in the new century will be an HPC. Key words: Characteristics; development trend of high-performance concrete; define 目 录 摘 要………………………………………………………………………………………1 Abstract…………………………
