Producing water-resistant gypsum compositions requires the use of finely dispersed additives that foster the formation of slightly soluble compounds coating the calcium sulfate dihydrate crystals, linking them and forming a dense and solid matrix of the material. This study dealt with the influence of the complex fine additive which includes metallurgical dust and multi-walled carbon nanotubes on structure and properties of gypsum binder. The adding additive to gypsum compositions will improve the bending and compressive strength characteristics by 70.5% and 138%, respectively, increase the water resistance of the material due to the synergistic effect of the modifiers. The integrated use of metallurgical dust and carbon nanosystems leads to profound transformation of the matrix structure, i. e. between the primary gypsum crystals the amorphous phase is formed binding the gypsum crystals in large block aggregates and protecting from water.
