Hygric and thermal properties of lime plasters modified with wood chips ash-based mineral admixture

Original language description

Information on plasters hygrothermal performance is of the particular importance for their applicability, especially in such applications, where high moisture content of the substrate is anticipated. Among such applications belong above all historical and older buildings, where horizontal water-proof insulation is usually missing. Therefore, hygric and thermal properties of newly developed lime plasters modified with wood chips ash-based mineral admixture are studied in the paper. As wood chips ash is pozzolana active, in plasters composition, lime hydrate was partially substituted by wood chips ash coming from biomass incinerator for heat and electricity production. The replacement ratio was 5, 10, and 15 mass % respectively. The dosage of batch water was maintained similar for all tested plasters. For basic characterization of studied materials, their bulk density, specific density and total open porosity were measured. Among hygric properties, apparent moisture diffusivity, water absorption coefficient, saturation moisture content and water vapor transmission parameters were accessed. As heat transport and storage significantly affect plasters performance in a real environment, their thermal conductivity and volumetric heat capacity were measured. Since the total open porosity was almost similar for all tested plasters, and their hygric and thermal properties varied in dependence on lime hydrate substitution, additional pore size distribution measurement was performed for explanation of obtained data. Based on performed test and accessed data, wood chips ash was found to be an alternative eco-efficient mineral admixture applicable in plaster mix composition.
