摘　　要：利用发泡剂、聚丙烯纤维、碱激发矿渣和生土制备的多孔屋面材料,能在多孔结构中储存大量雨水,通过水分的被动蒸发来达到降低室内温度的效果。通过分形理论研究表明:材料中孔的分形维数越大,蒸发降温效果越好。覆盖该多孔材料作为屋面表层后,室内温度明显低于普通屋面层。The porous roofing material made of blowing agent polypropylene fiber alkali-activated slag and raw soil can store alarge amount of rain water in the porous structure and achieve the effect of lowering indoor temperature by passive evaporation ofwater. The study of fractal theory shows that the larger the fractal dimension of pores in the material is, the better the evaporativecooling effect is. When the porous material is used as the surface of the roof, the indoor temperature is obviously lower than that ofthe common roof.
