CHRYSO uses a combination of admixtures which provides unrivalled performance in terms of robustness, workability retention, pumping and durability for this major construction site.
CHRYSO meets requirements through its EnviroMix® approach, particularly, in terms of deflocculation and viscosity control.
Concrete fluidity is maintained despite a relatively low water / cement ratio and a high rate of binder in the concrete.
CHRYSO demonstrates that this specific concrete mix design allow to answer challenging requirements, as durability guarantees : structure's specification is 120 years service life.
CHRYSO conducted several specific durability performance trials in laboratory to meet project specifications and to optimize the formulation of concrete CHRYSO technical experts provided solutions in connection with the performance-based approach and defined with the customer recommendations on formulations and adequate admixtures solutions.
