三峡工程碾压混凝土配合比研究

Mix Proportion Study of Roller Compacted Concrete for Three Gorges Project

为加快三峡工程建设，降低工程费用，拟在纵向围堰及三期上游横向围堰采用全断面碾压混凝土修筑。大坝主体建筑物某些坝段或部位也拟采用碾压混凝土。根据设计要求，结合三峡工程的具体情况，对碾压混凝土的配合比进行了系统研究，并提供了其物理力学性能试验成果。

For quickening project construction and reducing construction costs ,according to the designrequirement and project specific conditions,the mix proportion of the roller compacted concrete(RCC)which will be used in the longitudinal and 3rd stage upstream trasversal cofferdams and in thesome dam sections of the Three Gorges Project is studied.The test results of mechanical properties ofthe RCC are provided.
