Vacuum Concrete Mixer

The vacuum concrete mixer is an intensive mixer which enables to produce advanced and innovative concrete types by mixing under vacuum conditions. It is an important element in the development of new cementitious materials. The vacuum concrete mixer is an EIRICH R08VAC mixer with a capacity of 75 liter, combined with a smaller EIRICH R02VAC vacuum mixer with a capacity of five liter enabling an experimental study on paste and mortar level, or even on powder level. According to the manufacturer, the Magnel Laboratory is the only concrete research laboratory worldwide having a large capacity concrete vacuum mixer.
