摘　　要：为适应现代工程对C120超高强高性能混凝土的需要,项目以拟定水胶比为核心,通过逐级筛选的方法,确定了混凝土配合比所需各种原材料;通过大量平行试验,确定了混凝土配合比。同时,比较详细地研究了C120超高强高性能混凝土耐久性,研究得出结论,该混凝土工作性、力学性和耐久性能都大大优于一般高强混凝土和相关标准、规范要求。该混凝土具有良好的工程应用前景。In order to meet the needs of modern engineering for C120 ultra-high strength and high performance concrete, the project takes the proposed water binder ratio as the core parameter, and determines various raw materials required for concrete mix proportion through step-by-step screening method. Through a large number of parallel tests, the concrete mix proportion is determined. At the same time, the durability of C120 ultra-high strength and high performance concrete is studied in detail. It is concluded that the workability, mechanical properties, and durability of the concrete are much better than those of general high strength concrete, relevant standards, and specifications. The concrete has a good engineering application prospect.
