The impact of alkaline stimulation on the rheological properties of municipal solid waste incinerator bottom ash

The effective management of domestic waste incineration slag is a significant challenge that requires careful consideration. To optimize the utilization of municipal solid waste incinerator bottom ash (MSWI BA), it is critical to investigate the impact of activator modulus and incorporation levels on the rheological properties of slurry produced from alkali-activated domestic waste incineration slag. An experimental study was conducted to assess the rheological behavior and parameters of slurry produced from MSWI BA under varying activator concentrations and incorporation conditions. A constitutive equation was developed to characterize the slurry's rheological behavior. The findings indicate that slurry with varying activator incorporation levels and modes exhibits similar rheological properties. Variations in incorporation levels significantly affect shear stress, yield stress, and plastic viscosity in slurry with different activator types.
