The rheology of cementitious suspensions is dependent on various factors like solid content, particle size distribution and chemical composition. Moreover, the rheological parameters are reliant on shear history, which affects the formation of the particle network and thus the interparticle forces as the origin of yield stress and viscosity. To investigate the effect of shear time on the apparent state of flocculation and rheological performance, tests were conducted regarding the effect of the mixing time on the apparent particle size distribution using Focused Beam Reflectance Measurement (FBRM) and compared to actual measured rheological parameters in a rheometer.     «
