Abstract: In the present paper results on the hydration kinetics of cement paste with small amounts of very fine filler additions are presented. In the first days of hydration very fine inert fillers show a distinct impact on hydration processes that exceeds the simple filler and dilution effect. The influence of the specific surface area, the mineralogical characteristics and the electric potential on the coagulation behavior and the distribution of the filler particles in the fresh suspensions are discussed. Hypotheses are presented to explain the influence of those parameters on hydration kinetics. Based on the results, suggestions are made for the realistic modeling of hydration kinetics of cement pastes with very fine inert fillers.
