水下不分散混凝土研究综述

Review on Underwater Non-Dispersive Concrete

摘要: 我国水利水电、海洋工程、地下工程等领域的建设规模不断扩大，水下浇筑施工场景日益增多，对混凝土的水下施工性能提出了更高要求。水下不分散混凝土作为一种特殊功能混凝土，通过掺入抗分散剂(絮凝剂)实现水下不分离、自密实、低泌水的特性，有效解决了普通混凝土水下浇筑易离析、强度不足、施工质量难以控制等难题。本文在搜集国内外相关文献资料的基础上，介绍了目前水下不分散混凝土的研究现状及进展，论述了水下不分散混凝土的核心研究内容、研究进展以及主要研究方向等方面，对水下不分散混凝土目前的研究现状、在研究和应用中存在的问题进行进一步具体分析，为其后续研究与工程应用提供参考。

Abstract: The construction scale of water conservancy and hydropower, marine engineering, underground engineering and other fields in China is constantly expanding, and the number of underwater pouring construction scenarios is increasing, which puts higher requirements on the underwater construction performance of concrete. Underwater non-dispersive concrete, as a special functional concrete, achieves the characteristics of non-separation, self-compaction, and low bleeding underwater by adding anti dispersing agents (flocculants), effectively solving the problems of easy segregation, insufficient strength, and difficult construction quality control of ordinary concrete poured underwater. Based on the collection of relevant literature at home and abroad, this article introduces the current research status and progress of underwater non-dispersive concrete, discusses the core research content, research progress, and main research directions of underwater non-dispersive concrete, and further analyzes the current research status, problems in research and application of underwater non dispersive concrete, providing reference for its subsequent research and engineering applications.
