Controlling the rheology of concrete for the combined use of plasticizers/retarders and accelerators

Within modern concrete technology combinations of admixtures are widely used. These combinations will be studied more in detail in this project. The proposed research project has the following main objectives: The determination of the physico-chemical interaction: (a) in-between the admixtures and (b) between the admisxtures and the cement and the mineral additions. The quatification and modelling of the effect of the combined use of admixtures on the rheological behaviour of concrete.
