| Sumario: | Basalt fiber can serve as a substitute for synthetic fiber in gypsum-reinforced materials. Similar installation materials have been used in the Green Installation Programme. Other types of fibre, including basalt dust, that have not previously been considered are also attracting much attention. It forms during dry dust removal and is an available waste from the production of basalt materials. In addition to industrial dust wastes, it is proposed to use recycled bottom ash as a dispersed filler as an additional component. During its processing, coarse fractions were removed from the ash and the content of the organic part was reduced. The purpose of this study is to explore the possibilities of an organomineral complex of additives based on basalt dust, recycled bottom fuel ash and a hyperplasticizer Melflux 2641F to improve the properties of gypsum materials. Varying the components of the organomineral complex causes a change in the properties of the resulting composition: increasing the density and compression and rupture strength, reducing water absorption. An increase in the physical and mechanical characteristics of the gypsum composite with the introduction of basalt dust and bottom ash is associated with obtaining a denser particle due to an optimally selected granulometric structure and obtaining effective gypsum composites with an optimized internal structure. The microscopic structure of the modified gypsum composite with an organomineral complex of additives was established using scanning electron microscopy (SEM). The organomineral complex changed the structure of the gypsum stone and energizing the formation of intergrowth contacts with each other. |
