AbstractAbout AuthorsReferences
Mineral filler is the most important component of gypsum and anhydrate mixes. Technical and operational properties of mixes depend on the intensity of interfacial interaction between the matrix and the mineral filler. The production of activated mineral fillers with principally new characteristics is provided by the use of mechanical activation and chemical modification of their surfaces due to creation of new surface nano-structures. The formation of nano-structures is carried out by fixing the modifier according to the mechanism of molecular layering on the surface of the filler in the process of its obtaining when grinding and activating the mineral component. The principles of selecting chemical modifiers for activated fillers depending on the type and purpose of gypsum and anhydrite mixes are established. Physical-technical and operational properties of gypsum and anhydrate mixes with activated fillers are determined.
