随着社会主义市场经济体制的建立与完善,我国的城市化进程不断加快,国内各地的结构工程项目如雨后春笋般纷纷涌现出来,呈现了一派繁荣景象。作为结构工程的重要施工材料,高强混凝土具有较多的优势,诸如密实性好、强度等级高、耐久度佳等,因此被广泛运用于大跨度桥梁、高层建筑等工程建设中。要想提高混凝土的各种使用性能及质量,并延长混凝土构件的使用寿命,就必须对高强混凝土的配合比进行有效的控制,同时提高其配合比的设计效果,进而提高结构工程的整体质量及投入使用后的各种性能。
With the establishment and improvement of the socialist market economic system, the process of urbanization in our country continues to accelerate. Structural engineering projects in various parts of the country have mushroomed in succession, showing a prosperous scene. As an important construction material of structural engineering, high-strength concrete has many advantages, such as good compactness, high strength grade and good durability. Therefore, it is widely used in construction of large-span bridges and high-rise buildings. In order to improve various performance and quality of concrete and extend the service life of concrete components, it is necessary to effectively control the mix proportion of high-strength concrete and to improve the design effect of the mix ratio so as to improve the overall quality of the structural engineering and Put into use after a variety of performance.
