Resumen
Filling material for construction. The invention relates to a filler material as an additive or filler used in mixtures for pastes and mortars with a sulphate matrix (calcium, phosphogypsum, boroyeso, fluoroyeso, titanoyeso ...) of natural or recycled origin, also known generically as plasters and plasters, as well as with calcareous and/or dolomitic matrix, for the improvement of thermal conductivity, reduction of electromagnetic wave transmission (electromagnetic screen) and improvement of the resistant mechanical behavior of these elements. This material can be used in pastes with plasters, plasters or mixtures of both, even with additions of lime and dolomites in simple elements (coatings or fillers) or composite or multilayer (multilayer panels, gypsum board), being an inert material and physically and chemically stable over time. It allows to give greater versatility to the elements that need a better transmission of thermal energy, allowing to increase the size of industrial or prefabricated elements. It can also be used as cargo or filling simply, thanks to its low cost. (Machine-translation by Google Translate, not legally binding)
