Abstract

Lime plasters containing waste brick powder in different quantities (10%, 30%, and 50% of mass) as a partial replacement of silica sand and lime are studied. A common lime plaster is used as a reference. Experimental investigations include the measurement of basic physical properties (water vacuum saturation method and helium pycnometry), pore distribution (mercury porosimetry) and water vapor transport properties (cup method). The open porosity and water vapor diffusion coefficient are found to increase with the increasing brick powder content.
