摘　　要：以硫铝酸盐水泥和脱硫石油焦灰为复合胶凝材料,基于双氧水发泡工艺制备发泡保温材料。研究了水胶比和发泡剂用量对脱硫石油焦灰—硫铝酸盐水泥发泡体系抗压强度和干表观密度的影响。试验结果表明,水胶比相同时,发泡水泥的干表观密度和抗压强度均随发泡剂用量增加而降低,而抗压强度在发泡剂增加到一定程度时趋于稳定;发泡剂用量相同时,干表观密度随水胶比增加而先增加后降低,抗压强度随水胶比增加总体呈上升趋势。其中当水胶比较低时,试块强度增长较快;当水胶比较高时,试块强度趋于稳定。Using sulphoaluminate cement and desulfurization of petroleum coke ash as composite cementitious materials, foaming thermal insulation material is prepared by hydrogen peroxide foam system. The influence of water-binder ratio and amout of foaming agent on compressive strength and dry bulk density of petroleum coke ash-sulphoaluminate cement foaming system is studied. The experiment results show that, at the same water binder ratio, while the amount of foaming agent increases, dry bulk density of foam cement and compressive strength decreases. The compressive strength of foam cement tends to be stable in some certain degree with the increasing of foaming agent; as the same amount of foaming agent, dry bulk density increases at first then decreases. With the increasing the water-binder ratio, the compressive strength increases in general. When the water binder ratio is relatively low, strength of block increases rapidly; while the water binder ratio is high, the strength of block tends to be stable.
