  • Retarding Admixture an overview ScienceDirect Topics

    Some chemical admixtures are designed to allow for an extended set control of the freshly mixed concrete Most extended setcontrol admixtures comply with the requirements of ASTM C494/C494M17 (2017) as a Type B, retarding admixture, or Type D, waterreducing and retarding admixture These admixtures are often referred to as hydration control

  • Set Retarding Chemical Admixtures SpringerLink

    There are three types of retarding admixtures recognized by ASTM: Type B, which simply retards the hydration of the portland cement; Type D, which not only retards the hydration but also acts to disperse the cement and thereby provide water reduction; and finally Type G, which is a high range water reducing and set retarding admixture [2]
