摘　　要：发泡水泥是以水泥为主要胶凝材料,通过化学发泡工艺制成的一类轻质多孔材料。对发泡水泥孔结构的控制技术进行了系统研究。结果表明:通过改变水料比、增稠剂和稳泡剂掺量可实现发泡水泥孔径的控制;随着平均孔径逐渐增大,发泡水泥的抗压强度呈现先提高后降低的趋势,平均孔径在1200μm左右的发泡水泥具有较高的抗压强度。提出了具有较高抗压强度和适宜孔径的发泡水泥配合比。Foam cement is a kind of light and porous material prepared with cement as the main binding material through chemical foaming process. The control technology of pore structure of foam cement is researched in this paper. The results show that the pore structure of foam cement can be controlled by changing the ratio of water, thickening agent and foam stabilizer content. With the gradual increase of the average pore diameter,the compressive strength of the foam cement shows first increase and then decrease. When the average pore diameter is about 1200 μm, the compressive strength of foam cement is higher. The suitable mix proportion of foam cement with high compressive strength and suitable pore structure is proposed.
