In this study, to secure the volume stability of the lightweight foamed concrete, the relationship between the rheological parameters and foam breaking of the lightweight foamed concrete are analyzed. From the obtained relation, it was found that the higher plastic viscosity and yield stress can provide volume stability by reducing foam breaking. |
