During the construction of the Tunnel de Champel in Geneva, MasterEase from Master Builders Solutions proved to be a well suited superplasticizer for sprayed concrete. MasterEase reduces the viscosity of the concrete, making it less sticky and therefore easier to pump and apply. This is a significant advantage for sprayed concrete applications. MasterEase UG 3904 increases the workability time and, when applied, the concrete hardens more evenly on the tunnel wall.

Thanks to the use of MasterEase, the Swiss tunneling contractor Marti Tunnelbau AG was able to switch to a more economical cement...
