Cement paste with lower water-cement ratio of 0.25. The electrochemical spectroscopy (EIS) used for assessing the evolution of the rheological properties of fresh cement paste. Effect of high range water reducing admixture on EIS. The parameter of Rct in EIS closely related to the fluidity of cement paste tested by mini cone.
