Experimental Research on RCC Construction Technology

As far as the RCC dam construction of Pengshui Hydropower Station concerned some problems,an experimental research on mixing technology,roller compaction technology,layer surface treatment and construction technology of GEV-RCC was performed.Through specimens taken from a mixing plant,core boring and water pressure tests and field shear tests,the rollability and rationality of the mix proportion of concrete selected through laboratory tests were validated and suitable construction technology was determined.The test results provided a basis for project construction.
