Abstract
With the acceleration of the urbanization process and the continuous advancement of the infrastructure construction, the requirements for building materials are increasing day by day. Traditional concrete is difficult to meet the demand in some special projects, such as the structural bearing capacity of high-rise buildings, the wind resistance of large Bridges, and the radiation resistance of nuclear power plants. Therefore, it is very important to study the technology and application of high-performance concrete. As a kind of concrete, high performance concrete, a new building material with high strength, high durability and high performance, can meet the higher requirements of modern engineering for concrete performance, improve the safety and sustainability of the project, and reduce the cost of maintenance and repair. This paper summarizes the research background, performance characteristics, preparation technology and application field of high performance concrete. Firstly, the necessity of high-performance concrete research is explained from the aspects of accelerated urbanization process, increased engineering demand and environmental protection. Secondly, the concept and performance characteristics of high performance concrete are introduced in detail, including its high strength, high durability, good work ability and environmental protection. Through the laboratory test method and engineering example analysis, the key links of mix ratio design, construction control and quality inspection are discussed. Finally, we summarize the wide application prospect of high performance concrete in infrastructure construction, commercial and residential construction, water conservancy engineering and special engineering, and prospect its future development trend.
