Abstract: The effects of foaming agent addition, water-cement ratio and foaming temperature on the foaming process, the dry density and compressive strength of the foamed body with polystyrene foam particles addition or not were investigated. The results showed that the slurry foaming ra-tio first increased and then decreased with the increase of foaming agent, water-cement ratio and foaming temperature, while the dry density and the compressive strength of the foam changed in the opposite trend simultaneously. Before adding foamed plastic particles, the foaming temperature was the main effect factor for the dry density of the foamed body, and the water-cement ratio was the main effect factor for the compressive strength of the foam. After the addition of polystyrene foam particles, the slurry foaming ratio reduced significantly, the foaming temperature was also the main effect factor for the dry density of the foamed body, while foaming agent addition, water-cement ratio and foaming temperature were the main effect factors for the compressive strength of the foam. The foamed body with lower dry density and higher compressive strength can be prepared by organic-inorganic composite foaming under the conditions of lower foaming agent content (3‰—5‰), higher water-cement ratio (0.46) and lower foaming temperature (30—40 ℃)
