Abstract:
Presents three experimental programs employing high-range water-reducing admixtures to modify durability performance in portland cement-fume concrete. Resistivity and chloride permeability are shown to be significantly improved where fume-replaced concrete uses superplasticizers. Superplasticizing has some demonstrated drawbacks where fume is introduced to reduce alkali aggregate reactions.
