TY - CONF A1 - Crasselt, Claudia A1 - Schmidt, Wolfram A1 - Sturm, Heinz T1 - Influence of rheology modifying admixtures on hydration of cementitious suspensions N2 - The presence of polycarboxylate ether (PCE) based superplasticizers (SPs) has an enormous influence on the early hydration of cement. Therefore, the talk presents first experimental results about the influence of a delayed addition time of PCE SPs on the hydration of cement and tricalcium aluminate (C3A) pastes, investigated by isothermal heat flow calorimetry and in-situ XRD.
