水下不分散混凝土配合比设计

不分散混凝土的质量在很大程度上取决于混凝土的抗分散性和流动性,由于水下混凝土一般不允许振捣,因此,在水下不分散混凝土配合比设计时必须更多地考虑其流动性和抗分散性。以曹妃甸港区原油码头靠船墩和系缆墩的水下封底混凝土为例,介绍水下不分散混凝土配合比设计中应注意的问题。

Mixing Proportion Design of Non-dispersible Underwater Concrete

The quality of non-dispersible concrete depends greatly on anti-dispersive property and liquidity of concrete.Generally,vibration is forbidden for underwater concrete,the liquidity and anti-dispersive property should be considered in the design of the mixing proportion of non-dispersible underwater concrete.Taking the berthing and mooring dolphin of Caofeidian crude oil pier as an example,the relative problems should be paid attention to in the design of it are introduced.
