Setting Velocity of Cement Pastes and Monolithics - The Impact of Mixing This paper reports on the results of a science project conducted during the last two years. In this project a focus was set on the rheological and setting properties as a function of the mixing energy applied in dry and wet state. A proper adjustment of mixing time and velocity even prior to the water addition is a powerful measure to enhance the compaction properties of concretes. The products are more homogenous and show improved properties with special regard to their rheology, density, open porosity and mechanical strength.
