汾河二库大坝碾压混凝土施工质量控制

Quality Control of Roller Compacted Concrete Dam Construction of the Fenhe ReservoirⅡ

汾河二库地处北方干旱地区,气候特点气温高、湿度低、干燥、多风、昼夜温差大,很不利于碾压混凝土的施工质量,针对这些不利的气候条件,我们采用了必要的工程措施,精心施工,取得了令人满意的工程质量。本文从施工质量控制方面介绍汾河二库大坝碾压混凝土的原材料选定、配合比设计、VC值控制、层间结合质量控制及压实容重的检测与控制。

In this paper, the quality control of R.C.C dam construction including the items from selecting of row material to detecting and controlling of compacted bulk density are introduced.
