Abstract：The influence of blast furnace slag(BFS)content on the properties of BFS-fly ash based foam geopolymers were discussed. Different amounts of BFS(0,10%,30%,50%)were applied in preparation of BFS-fly ash based foam geopolymers. Vis-cosity,density,porosity,compressive strength,flexural strength,SEM,and XRD were employed to analyze the properties of foam geopolymers. The results showed that the optimized compressive strength and flexural strength were 1.66 MPa and 0.97 MPa with 30% BFS,density of 433 kg/m3,and porosity of 49%.
