Effect of Early Strength, Retarding and Slump-retaining Components of Polycarboxylic Acid Admixture on Workability of Fresh Concrete

Abstract The effects of the amount of early strength components, retarding components and slump-retaining components of concrete admixtures on initial fluidity, slump loss and initial setting time of concrete are compared through experiments, so as to adjust the workability of fresh concrete more pertinently.
