Abstract The efficient utilization of resources such as steel slag and fly ash is the focus of research in field of resource utilization in China. The preparation of porous sound-absorbing materials from waste is an utilization approach with high added value. Porous sound-absorbing materials were prepared by organic foam impregnation method using steel slag and high-alumina fly ash as raw materials. The relationship between solid content and thickener with slurry viscosity was studied by inner cylinder rotation method, and the effects of solid content and thickener on the microstructure, sound absorption and mechanical properties of sintered materials were also studied. The results show that slurry viscosity increases with the increase of solid content and thickener content at low shear rate. As the shear rate increases, slurry viscosity gradually decreases and remains stable after reaching a certain shear rate, while the shear stress gradually increases. The compressive strength and flexural strength of sample gradually increase with the increase in solid phase content, while the pore size and porosity gradually decrease. Additionally, the sound absorption performance exhibits a trend of first increasing and then decreasing. The sound absorption and mechanical properties of the material can be enhanced by formulating slurry with excellent fluidity and high concentration of solids. The main crystal phase of sample prepared by optimal process (sintering at 1 160 ℃ for 1 h) is anorthite, the volume density of sample is 573.98 kg/m3, the compressive strength is 1.0 MPa, and the average sound absorption coefficient is 0.47.
