CHRYSO expertise
The construction site represents a total volume of 43,000 m3 of concrete.
2200 m3 of Mass Concrete footing were used at ground level.

Beyond excellent early strength performance, CHRYSO®Fluid Optima 258 EMx allowed for very good workability retention and pumpability.
It provided the capability to pump 300m³/hour with 4 pumps and with optimal mixer truck rotation time.
