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.
