摘要：The mix ratio of high performance concrete for urban integrated pipe gallery should be determined according to the structural form, construction method and environment in which the structure is located. The performance, mix design, mix properties and durability of high-performance concrete raw materials used in urban integrated pipe gallery can be studied, and the mix ratio of concrete used in the project is finally determined. The relationship between each other is studied through a model. The actual engineering construction practice shows that the optimized high-performance concrete mix ratio of this study takes into account the workability, mechanical properties and durability requirements of concrete for urban integrated pipe gallery, and achieves good use results.
