“…Once more the passing and filling ability of the model concrete mixes were not studied in this exercise leaving much to be done to evaluate the flowability potential of the concrete. In an effort to pursue the net-zero protocol of the UNSDGs and COP27 for the year 2050 towards carbon neutrality in engineering design and infrastructural development, Taleb et al 42 investigated the effect of natural pozzolana (NP) as a partial replacement for Portland cement in self-compacting concrete mixes. This procedure was modeled with MBM and H–BM techniques considering a slump test configuration to study the YS and PV of the mixes.…”

Studying the rheological behavior of concrete, especially self-compacting concrete is vital in the design and structural integrity of concrete structures for design, construction, and structural material sustainability. Both analytical and numerical techniques have been applied in the previous research works to study precisely the behavior of the yield stress and plastic viscosity of the fresh self-compacting concrete with the associated flow properties and these results have not been systematically presented in a critical review, which will allow researchers, designers and filed operators the opportunity to be technically guided in their design and model techniques selection in order to achieve a more sustainable concrete model for sustainable concrete buildings. Also, the reported analytical and numerical techniques have played down on the effect of the shear strain rate behavior and as to reveal the viscosity changes of the Bingham material with respect to the strain rate. In this review paper, a critical study has been conducted to present the available methods from various research contributions and exposed the inability of these contributions to revealing the effect of the shear strain rate on the rheological behavior of the self-compacting concrete. With this, decisions related to the rheology and flow of the self-compacting concrete would have been made with apt and more exact considerations.
