The possibility to obtain new eco-compatible building materials by milling, pressing and direct sintering of secondary raw materials (SRM) derived from a physical/mechanical treatment of municipal solid waste incinerator (MSWI) bottom ashes is discussed. The chemical compositions and particle size distribution of used SRM press powders were evaluated using XRF analysis and by laser granulometer, respectively. The thermal and densification behaviours were studied by non-isothermal DTA-TG and dilatometric techniques...

The feasibility to substitute feldspar raw materials in a porcelain stoneware body with waste Cathode Ray Tube (CRT) glass was investigated. Various compositions, containing different percentages of feldspars and CRT glass, were compared. The densification process was studied by non-isothermal dilatometry and the degree of sintering was evaluated by pycnometric techniques. The structure and phase composition of the final ceramics were studied by SEM and XRD, respectively. The technological parameters and the mecha...
