For an assessment of the hygrothermal performance of renewed plasters in reconstructed historical buildings, it is necessary to determine basic thermal and hygric transport and storage properties. In this paper, moisture diffusivity, water vapor diffusion coefficient, sorption isotherms, thermal conductivity, specific heat capacity and linear thermal and hygric expansion coefficients of a lime-pozzolana plaster mixture with metakaolin as the pozzolana material are determined. Comparative measurements with common lime plaster are done as well. On the basis of the measurements performed, the suitability of the newly developed plasters for an application in reconstruction of historical buildings is assessed.
