An experimental investigation into the rheological properties of High-strength cement paste (HS-CP) and High-strength Self-consolidating concrete (HS-SCC) is presented in this paper. The study is intended at evaluating the effect of varying w/b ratio, PCE admixture, and incorporation of fly ash on the rheological properties of HS-CP and HS-SCC. The study emphasizes on determining the yield stress and plastic viscosity (Bingham constants) of HS-CP and HS-SCC. The devices Brookfield DV-II Pro Viscometer and ICAR Rheometer are used to determine the rheology of HS-CP and HS-SCC respectively. The individual and combined effects of four different w/b ratio (0.275, 0.3, 0.325 and 0.35) and fly ash (partial replacement 25% by wt. of cement) on the rheology are thus observed and analyzed. The results showed that both w/b ratio and fly ash had an impact on the rheology of HS-CP and HS-SCC. The devices used in this study were found to detect systematic changes in the rheology of HS-CP and HS-SCC
