| Abstract: | In the process of production and construction, the self-compacting concrete (SCC), known for its workability performance, exhibits a shear thickening and shear thinning phenomenon. In view of the significant influence of shear thickening and shear thinning behavior on the construction process and construction quality of SCC, the research development of shear thickening and shear thinning behavior of SCC is summarized. The mechanism of shear thickening and shear thinning of SCC is described. The characterization methods for shear thickening and shear thinning of SCC are compared. The influence factors of shear thickening and shear thinning behavior of SCC are analyzed. The research prospects of shear thickening and shear thinning behavior of SCC are discussed. |
