<p>Porous material formed of sintered mineral particles. It has an open porosity of 30-40 % by volume, a water permeability at 20oC varying to 0.6 to 60 m3/h.m2.bar for a wall thickness of 1 cm. when the medium diameter of the pores varies from 2 to 20 microns and a crushing resistance, measured in isostatic compression conditions, from 4.108 to 5.108 N/m2.</p> |
