Abstract
The application of supplementary cementitious materials (SCMs) in concrete preparation is an important strategy for advancing the high-performance and low-carbon development of modern concrete. However, the addition of SCMs alters the rheological properties of concrete mixtures, which in turn affects the workability of fresh concrete. This paper presents a review of relevant studies on the influence of SCMs on the rheology of fresh concrete. The rheological models applicable to fresh concrete, such as the Bingham model, the Herschel-Bulkley model, the modified Bingham model, and other models, are introduced in detail. The influence of SCMs, including fly ash, granulated blast-furnace slag (GBFS), silica fume, limestone powder, and steel slag powder, on the rheological properties of fresh concrete is comprehensively analysed and discussed. The intrinsic relationship between the rheology and workability of fresh concrete, as well as the influence of SCMs on flowability and stability, are systematically elaborated.
