流态化水下不分散混凝土的工程应用

Engineering Application of Flowing Anti-washout Underwater Concrete

文章介绍了流态化水下不分散混凝土在胜利油田进海路工程及秦山核电站海底取水口稳管工程中的应用情况。根据二者对混凝土流态化和泵送的要求,结合混凝土强度、水灰比、泵送距离及塌落度保持时间等条件,论述了泵送水下不分散混凝土絮凝剂和新拌混凝土性能的研制和改进。

You have been introduced respectively the applications of flowing anti-washout underwater concrete in Shengli Oilfield and Qinshan Nuclear Power Plant of China. According to the requirements of concrete compressive strength, water cement ratio, pump placing and slump retention and the filed circumstances, the improving process of flowing anti-washout underwater concrete admixtures are discussed.
