Sinter particulates (SPs) retained in the electrostatic precipitator of the sintering stages in a steelmaking plant were incorporated up to 20 wt% into kaolinitic clay to produce improved porous ceramics for building construction. Specimens were prepared by uniaxial press-molding and then fired at 750, 900 and 1050 °C that are typical temperatures for bricks, blocks and tiles production. Ceramic properties and microstructure related to porosity and mechanical strength were evaluated. The results disclosed, for the first time, how porosity might be associated with improved strength in clay ceramics processed at typical temperatures for bricks, blocks and tiles. Owing to the porosity, the ceramic thermal an acoustic insulation were also improved. Keywords: Sinter particulates, Porous clay ceramic, Improved properties |
