Slump Loss - an overview ScienceDirect Topics

Slump retention was also found to depend on the amount of dispersant remaining in the aqueous phase. For concrete with an extended slump life, PCE polymers with lower initial adsorption (i.e. PCE polymers with higher grafting density) should be preferred to fast and high adsorbing PCE polymers (Vickers et al., 2005).Another possibility for increasing slump life is to use reactive polymers.
