Rheological behaviour of gypsum plaster pastes with polyamide powder wastes

► The effect of polyamide powder waste on rheological properties of plaster is studied. ► Thixotropy, yield shear stress and plastic viscosity of the mixtures are analysed. ► The fluidity and viscosity of the pastes are function of the amount of polymer. ► Results justify the possibility of reusing polyamide waste in construction materials.
