Description
Summary:The application of renewable and waste materials for the production of building materials is currently one of the main trends, especially with regard to environmental aspects. This is a reduction in the volume of materials that could be a waste and at the same time a reduction in the cost (including carbon footprint) for special wood treatment products that would have to be produced. One example given in this article is the possible application of a mineralization of wood matrix by kiln dust produced in a cement plant. This treatment can be primarily used in the production of wood-based panels bonded with cement, whose main purpose is to limit the leaching of soluble components, which affect the setting of the cement. If the cement kiln dust is applied for the mineralization of wooden elements, the flammability of wood can be positively influenced. Bypass cement kiln dusts contain significant amount of chloride, which in this case function as a reducing agent. In this article, the effect of the wood mineralization by the cement kiln dust from CEMMAC a.s. Horné Srnie was investigated on thermal degradation of wood by a simultaneous thermal analysis TG / DSC.
