三掺技术在大体积混凝土中的应用

Application of Tri-mixture Technology in Mass Concrete

以河南平顶山某大厦基础工程大体积混凝土浇筑实际工程为例,介绍了UEA微膨胀剂、JKR复合减水剂及粉煤灰三掺技术在该工程中的应用情况。从原材料、配合比设计、施工管理、质检等方面进行全过程控制,取得了良好的技术及经济效益。

As the practical engineering of mass concrete grouting for a building basis project of Pingding mountain in Henan for an example,the tri-mixture technology of UEA micro-expansion agent,JKR composite water reducer and fly ash are introduced for the application on this engineering.Through the total process controlling from material,mix proportion design,construction management and quality testing,good technology and economic profit are acquired.
