白石水库工程通过现场碾压试验确定了主体工程所使用的碾压混凝土配合比及碾压遍数等工艺参数，同时在碾压试验中也暴露了碾压混凝土VC值增长过快、层间结合不良、骨料分离较严重等问题．在主体工程施工中对这些问题都采取了针对性的改进措施，取得了明显的效果，保证了主体工程碾压混凝土的施工质量． Through the on-site roller compaction test, the project of Baishi Reservoir confirms the process parameters such as the mix proportion of roller compacted concrete and the number of rolling compaction used in the main project, meanwhile, the roller compaction test also reveals that the VC value of roller compacted concrete rapidly increases, Bad, worse separation of aggregates and other issues. In the construction of the main part of these issues have taken targeted improvements and achieved significant results to ensure the construction quality of the main project of roller compacted concrete.
