摘要：
A permeable cement composition including an aqueous slurry of a hydraulic cement which is based upon a water-immiscible dispersed fluid phase and a hollow particulate material. The hollow particulate material breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.
