In this work thermal conductivity of ceramic tiles is investigated in order to assess their contribution to the building energy efficiency. The aim is to correlate microstructural and physical characteristics of ceramic tiles with their thermal conductivity. A porcelain stoneware tile has been selected as reference material. The contribution of the open and closed pores to thermal conductivity is investigated by using different percentages of polymethylmethacrylate (PMMA) as pore-forming agent and by varying the firing cycle. The evaluation of the experimentally measured values evidences the strong influence of microstructure and porosity of the materials on the thermal conductivity and diffusivity.

Abstract
In this work thermal conductivity of ceramic tiles is investigated in order to assess their contribution to the building energy efficiency. The aim is to correlate microstructural and physical characteristics of ceramic tiles with their thermal conductivity. A porcelain stoneware tile has been selected as reference material. The contribution of the open and closed pores to thermal conductivity is investigated by using different percentages of polymethylmethacrylate (PMMA) as pore-forming agent and by varying the firing cycle. The evaluation of the experimentally measured values evidences the strong influence of microstructure and porosity of the materials on the thermal conductivity and diffusivity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
