This work deals with the mechanical and filtering properties of porous materials based on silicon carbide and aluminate cement for filtration applications. Silicon carbide classified according to particle sizes was used as the main aggregate. The influence of granulometric composition and quantity of aggregate upon porous structure generation was studied and mechanical properties were characterized using a three-point bending test of columns with proportions of 20 × 20 × 100 mm prepared of testing mortars. The input materials were characterized using laser granulometry and X-ray diffraction; the porous structure was studied using mercury porosimetry, and scanning electron microscopy. Disc-shaped barriers with 90-mm diameters were prepared by uniaxial pressing in a mold. They were tested using air flux to determine their effective permeability. Additionally, capillarity testing of the materials was carried out.
