摘　　要：水下不分散混凝土的应用有效方便了水下环境中的混凝土施工。通过在混凝土中添加絮凝剂配制成水下不分散混凝土,使混凝土在水下浇筑过程中达到良好的施工性能和使用性能。实践证明,水下不分散混凝土能有效保证施工操作和施工质量。Underwater non-dispersible concrete can effectively facilitate concrete construction in underwater environment. By adding flocculating agent, an underwater non-dispersible concrete was prepared to ensure that the concrete achieve good workability and performance during underwater placement. The practice proved that underwater non-dispersible concrete can effectively guarantee the quality of concrete placing and concrete construction.
