In the presented study, new types of lightweight plasters for passive moderation of interior climate were designed and tested. The examined plasters were composed of blended mineral binder (cement-lime or gypsum-lime), silica sand, perlite, chemical additives, and batch water. For the basic characterization of studied materials, bulk density, specific density, and total open porosity were measured. The mechanical resistance of the developed plasters was assessed in flexural and compressive strength tests. The ther...

The research of 2D carbon-based nanomaterials has become very intensive since the discovery of graphene. Many different preparation procedures of graphene and graphene derivatives have been reported. The aim of this paper was to prepare and characterize partially oxidized graphite oxides, which were prepared from nanographite by adding different amounts of potassium permanganate as an oxidizing agent. The C/O ratio was evaluated from X-ray photoelectron spectroscopy, energy dispersive spectroscopy, and elemental a...
