清水混凝土属于内部质量和外观质量较佳的一类混凝土,近年逐渐在水工混凝土结构中有所应用。通过介绍四川省大渡河流域的长河坝水电站岩锚梁清水混凝土的工艺试验过程和施工取得成功的施工范例,充分揭示了清水混凝土的外表质量与模板工艺、浇筑工艺和混凝土配合比的内在联系。事实再次证明:欲取得清水混凝土较好的施工效果,进行必要的工艺试验以及总结并改进存在的问题是关键。

As-cast-finish concrete is generally applied by concrete for hydraulic structaare because better internal quality and appearance quality.It introduceed the success construction example which rock anchor beam as-cast-finish concrete technology testing process and construction m Dadu River Valley Slchuan Province of Changheba Hydropower Station.To fully reveal the relationship which concrete appearance quality and template technology, pouring process and concrete mix proportion.Once again proved that, it is the key that make the necessary technology test and the summary and improvement of the pr...
