文档介绍：摘要
随着我国改革开放和现代化进程的加快,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(High Performance Concrete,HPC) 由于具有高耐久性、高工作性、高强度和高体积稳定性等许多优良特性,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中的重要成果,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。

Abstract
As China's reform and opening up and modernization process accelerated, the scale of construction in China is growing, how to ensure construction quality, while also enable the safe use of project can go a long, increasingly at all levels of government munity attention. In many civil engineering construction, the concrete application of surface covered, and use many times that is rare. In particular, in recent years, a relatively new development and concrete technology is rapidly applied to many practical projects, and that is high performance concrete.
HPC (High Performance Concrete, HPC) as high durability and high workability, high strength and high volume stability and many other fine features, is considered the prehensive performance of the current world of concrete, has been in many important project has been adopted, especially in the bridge, high-rise building, harbor construction and other projects.
This paper describes the development of high performance concrete historical background and current status of domestic and foreign research to clarify the characteristics of high performance concrete, citing high-performance concrete applications in the important domestic and foreign research results, and prospects for its development trend. With the high level of construction and large-scale, modern development, HPC will e an important new century construction materials. 朗读
