Results of the effect of fly ash upon rheological properties of cement pastes have been presented. Bituminous fly ash when added to cement have been found to produce a decrease both in the yield shear stress value and plastic viscosity of cement pastes the greater the higher the fly ash content. A relation between the fine fraction share in the fly ash and the flowability degree of cement pastes was found. The fine fraction content of the fly ash has been proved to be a better parameter to evaluate the influence of the fineness upon the rheology of cement pastes than Blain's specific surface area is.
