As China's reform and opening up and modernization process accelerated, the scale of construction in China is growing, how to ensure construction quality, but also enable the safe use of the building down a long time, levels of government and increasingly widespread concern in the community . In many civil engineering construction, the concrete application of surface covered, frequency of use as much is obvious. Especially 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 rability and high workability, high strength and high volume stability and many other fine features, is considered the most comprehensive 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 become an important new century construction materials.热心网友 时间:2023-10-03 07:39
With China's reform and opening up policy and modernization advancement speeding up, our country the construction scale is enlarging, how to ensure the construction quality at the same time, also can make building long-term safety USES it by governments at all levels and, increasingly wide attention of all social sectors. In many of the civil engineering construction, the concrete application widely, use frequency is obvious. Especially in recent years, a relatively new concrete technology is rapidly developed and applied to many practical engineering projects, that is the high performance concrete.热心网友 时间:2023-10-03 07:40
