Título del libro: 8th Pacific Rim International Congress On Advanced Materials And Processing 2013, Pricm 8 Título del capítulo: Novel self-foaming cellular composites produced from recycled water potabilisation sludge
Cellular composite products with a glassy matrix were produced in a single-step process using mixtures of clay with sludge obtained from the flocculation process for drinking water potabilisation. At high temperatures, where a sufficient amount of viscous liquid phase is present, porosity is generated spontaneously, presumably by the release of H2O from hydroxyl-containing minerals. This allows the trapping of gas bubbles in the liquid without the use foaming agents or templates. Two variants of the process were tested, one producing the material in a mould and the second one without mould. In the first case, the retaining pressure exercised by the mould limits the escape of gas trough the liquid phase and a highly porous material is produced. Without mould, more gas can escape and less porosity is generated, resulting in a lightweight, high strength material consisting of non-connected pores in a composite of mineral grains in a glassy matrix.
