摘　　要：混凝土超缓凝剂技术是当今混凝土技术的一个新的研究方向。它是解决港工、水工结构、工业与民用建筑等大体积混凝土施工中的冷缝和温度裂缝问题、滑模施工中调节凝结时间等问题的行之有效的手段。文章介绍了一种最近研制成功的 WH- 新型液体水溶性混凝土超缓凝剂 ,并对其缓凝机理进行了探讨。The technology of super concrete retarder is a new research interest in concrete technology.The technology of super concrete retarder is an effective measure to control cold joints and thermal cracking in mass concrete construction in port works marine structures,and civil and industrial works.It is also the effective measure to control the setting time of concrete in concrete construction with slip-form.The paper presents an introduction to a newly developed WH-Ⅱ water-soluble concrete retarder which is a liquid type super retarder for concrete and a discussion on the set retarding mechanism of the new retarder.
