FLUIDIZING MIXTURE FOR A HYDRAULIC COMPOSITION.

摘要

Mixture for a hydraulic composition, comprising: an inerting agent for at least partly neutralizing the deleterious effects of impurities of the hydraulic composition on the workability of the hydraulic composition; a first superplasticizer that differs from the inerting agent; and a second superplasticizer that differs from the first superplasticizer and from the inerting agent and has a maximum fluidizing action at 20°C that occurs after the maximum fluidizing action at 20°C of the first superplasticizer.
