    In order to ensure the performance of concrete materials and achieve low-carbon and green development,two kinds of ternary cementitious systems were prepared by replacing 55% (mass fraction) cement (C) with auxiliary cementitious materials (SCMs) such as slag powder (GS),fly ash (FA) and limestone powder (LS),namely fly ash-slag powder-cement system (FGC) and limestone powder-slag powder-cement system (LGC). The influence of the proportion changes of FA-GS and LS-GS in system on compactness,workability,and strength of ternary cementitious material powder was studied,and the optimum mix ratio of ternary cementitious system was determined by microstructure analysis. The results show that as the proportion of GS in the two ternary cementitious systems increases,the compactness and flowability of sample slightly decrease,while the compressive strength,flexural strength,and environmental benefits of sample gradually increase. When the mass ratio of FA-GS and LS-GS is both 3∶8,the middle and late strength of mortar samples prepared by the two cementitious systems can be close to or even higher than that of pure cement samples.
