Abstract:
Segregation in concrete may be due to a too -fluid mortar to a relatively small volume of mortar or both, Powdered admixtures tend to reduce segregation by increasing the volume of mortar as well as furnishing a less fluid mortar for any required flowability. Rela- tive volume of paste obtained per unit weight of ad- mixture, with flowabilities the same, is a measure of admixture efficiency.
