高性能混凝土为一种能满足特殊性能和特殊用途的混凝土,仅采用常规材料、普通拌和、浇筑和养护等措施达不到高性能混凝土的要求,而是必须通过提高浇筑、捣实的方法来提高混凝土的长期力学性能、初期强度、刚度和体积稳定性以及延长其在恶劣环境下的使用寿命。因此,采用高性能混凝土对公路桥梁进行施工可以很大程度的避免事故的发生。在此分析了高性能混凝土的特性,并简要分析了高性能混凝土在公路桥梁建设中的应用。
High-performance concrete is a kind of concrete that can meet the special performance and special purposes. It can not reach the requirements of high-performance concrete only by ordinary materials, ordinary mixing, pouring and curing etc., but must be improved by pouring and tamping Improve the long-term mechanical properties of concrete, initial strength, stiffness and volume stability and to extend its service life in harsh environments. Therefore, the use of high-performance concrete bridge construction on the road to a large extent to avoid the accident. This paper analyzes the characteristics of high performance concrete, and briefly analyzes the application of high performance concrete in highway bridge construction.
