The resistance of ethyl silicate-consolidated bricks to sodium sulfate crystallization cycles was evaluated. A commercial ethyl silicate (ES) based product was applied by brushing with 5 or 10 strokes to assess the effect on distribution/accumulation of the consolidant inside the pores. After long-term curing, aimed at making ES-treated samples lose their temporary hydrophobicity, samples were characterized by assessing the penetration depth of consolidants, tensile strength and modifications in open porosity and pore size distribution. Resistance to salt crystallization was evaluated by carrying out sodium sulfate crystallization cycles. The capillary suction of the salt solution was let occur through the untreated surface of cubic samples treated in the upper face, in order to investigate brick response to salts coming from behind the consolidated layer (the situation usually occurring when rising damp is present). Treatment with either 5 or 10 strokes provided protection against ...

L\u2019utilizzo di finiture fotocatalitiche per il restauro architettonico richiede un\u2019attenta valutazione non solo della loro efficacia in termini di capacit\ue0 autopulente, ma anche della effettiva compatibilit\ue0 con i materiali pre-esistenti. In questo lavoro viene presentato uno studio preliminare sull\u2019applicazione di una finitura a base di TiO2 su intonaci di restauro, ai fini di una sperimentazione di tale tipo di trattamento nella facciata di un edificio settecentesco nel centro storico di Bologna

La directive 96/61/CE (aussi dite directive IPPC de controle integre de la prevention de la pollution) a introduit le concept de meilleure technique disponible (BAT) comme reference a la place du concept de normes de qualite pour l'environnement (EQS) pour la definition des mesures de prevention et de controle de la pollution de l'environnement. Une procedure specifique de gestion du cycle de vie (LCA), specifique a l'industrie des carreaux ceramiques, a ete developpee et utilisee pour comparer les performances vis-a-vis de l'environnement de differentes techniques et de leurs effets couples. La procedure LCA ainsi appliquee permet d'identifier les meilleures parmi les techniques disponibles.

Porcelain stoneware tilesare getting a prominent role on the market offering excellent solution either for interiors or for exteriors construction for flooring and coverings. This ceramic material meets the basic requirements to be compatible with different semiconductor deposition technique. Based on these consideration we investigated the possibility of using porcelain stoneware tiles as solar cells substrates for built-integrated photovoltaic applications. The compatibility of the commercial tiles with the solar cell fabrication process was successful proved and a conversion efficiency of more than 4% has been obtained on a small area devices as a preliminary result
