Abstract
Introduction: The currently available mixing systems are compared with regard to handling, mechanical properties and economical aspects. Methods: In 8 vacuum mixing systems the handling, pump performance, system tightness, the used air volume, the filter efficiency, the remaining amounts in the mixing system and the porosity of the cements are shown in comparison. Results: The individual examinations of mixing systems show enormous differences, which can be of significance to the user in the choice of system and, depending on the individual circumstances, can influence the quality of the mixed cement. Conclusion: The results enable the user to choose and handle a vacuum mixing system which is optimally suitable for the individual circumstances in respect to the characteristics examined.
