The possibility of using TPP slag as the raw material for the production of porous filler has been proved. This approach increases the savings of natural resources, reduces the cost of finished product and reduces the level of environmental pollution. Insignificant values of the pressure drop confirm the application feasibility of the filtration drying as an energy-saving method of the drying of slag and clay for the preparation of the charge for porous filler production. Obtained results on kinetics are useful for the organization and intensification of the filtration drying process of slag and clay as the preliminary stage at the porous fillers production line. The qualitative new porous filler with the bulk density of 230 kg/m3, the specific heat of 0,82 kJ/kg∙K, the thermal conductivity of 0,067 W/m2∙K and with a compressive strength of 27,7 MPa has been obtained which can be used for the production of lightweight concretes.
