摘要
随着我国改革开放和现代化进程的加快,我国的建设规模日益增大,如何保证建筑工程质量的同事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,并对其发展趋势做出展望。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
The construction scale of China is growing with the accelerated process of reform and opening up and modernization. How to ensure quality of construction works, while also enable the safe use can go a long? It is concerned by the government and society. Widely used in concrete and the use of so many times is rare in many civil engineering construction. Lately, a relatively new development and concrete technology is rapidly applied to practical engineering, that is, high performance concrete.
Because of the high durability and high workability, high strength and high volume stability and many other fine features, high performance concrete is considered as the world's prehensive concrete performance at current. It has already been used in many important projects, 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, clarifies its’ characteristics, cites the importance of domestic and foreign research results of the application, describes the development trend of the future. With the high level of construction, large-scale and modern development, high performance concrete will e an important new century construction ma
