| 土木工程中高性能混凝土材料特性研究 摘 要 高性能的混凝土（HPC）是通过使用现代化的混凝土制备技术制备的，它并非混凝土的品种。和一般的混凝土比较起来，高性能混凝土具有可持续发展性、广义性和动态性，是更加适合现代工程的施工的材料。并且具有跟环境相适宜的耐久性、体积稳定性、经济性和高工作性，这与传统混凝土是大不同的。在国内很多大型建筑工程、市政工程、水利工程等项目很多都在使用这个材料，它在运用过程中能对减轻自重、减少材料用量、保护自然环境、节约资源等要求非常严；在对高性能混凝土材料特性研究过程结果里能提高人们对高性能混凝土的认识、重视，为工程施工使用HPC过程中提供参考的作用，并且能提高混凝土的综合特性和工程结构使用时间。这样才能实现材料质量的提高和技术的发展，让高性能混凝土在工程应用中能发挥卓越的经济效益，推动经济建设发展。 关键词：耐久性、高工作性、体积稳定性、经济性 Abstract High performance concrete is concrete prepared with modern concrete technology. Relative to ordinary concrete, it is not a variety of concrete, but a combination of concrete that is suitable for industrial production and construction and takes the broad dynamic sustainable development as the basic requirement. High performance concrete (HPC) is a modern concrete technology in the 21st century. Compared with traditional concrete, the basic conditions of HPC are environment-appropriate durability, high workability, volume stability and economy. With the continuous improvement of the material quality of engineering structure and the continuous development of engineering technology, its application prospect will be more and more broad. Some large construction, municipal, water conservancy project is more use of high performance concrete, its in reducing the weight of concrete structure, reduce material consumption, environment protection, resource saving etc. We will strictly, for through study on characteristics of high performance concrete materials further raise their awareness of high performance concrete and emphasis, for high performance concrete materials, mix proportion design, provides some references for the construction process, so as to further improve the comprehensive properties of concrete, improve the use fixed number of year of engineering structures. In the project application to play a significant economic benefits, promote the pace of economic construction and development. Keywords: durability;high workability;volume stabilit;economy |
