This study investigates transformations of a pre-mechanically activated saponite-containing material with subsequent high-temperature treatment. The thermogravimetric analysis confirmed that the mechanical activation of saponite leads to the destruction of its layered structure, accompanied by the release of silicon dioxide and magnesium oxide in free form. The values of surface activity for mechanically activated saponite-containing material are also calculated. It is shown that when mechanically activated saponite-containing material is mixed with water, minerals of the serpentine group are formed, and further high-temperature treatment leads to the formation of minerals of the olivine group. It is experimentally shown that high-temperature treatment leads to the creation of a more durable structure of the saponite-containing material. This is due to decreased porosity and pore size, and sorption of moisture from the environment is also reduced. The study showed that saponite-containing waste materials can be effectively treated to create composite materials based on magnesia binders. Thus, with this method, the waste is effectively recycled into various green building material and can be used as supplementary cementitious material or fine aggregate replacement in concrete.

“…Based on the research, the authors showed that the binder makes it possible to produce a thermal insulation material on an industrial scale without changing the production technology of conventional mineral fibre wool. Moreover, the method of applying clay as a binder was successfully implemented in the production line at the Insulation Plant “Zavod Izolatsi” Irpen, Ukraine [ 14 ]. The second important factor affecting fibre durability is moisture content.…”

The structure and properties of the glass can be modified by introducing appropriate additives. Dolomite is one of the primary raw materials modifying the properties of glass, in which the essential component is calcium-magnesium double carbonate CaCO3∙MgCO3. The paper presents the research results on glasses obtained by smelting pure amphibolite and amphibolite modified with 10 and 20% dolomite additives. The raw material used was mined in the Poland region of Lower Silesia. The glass melting process was carried out in an electric furnace at 1450 °C for 2 h. The structure and properties of the glasses and crystallization products were determined by Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy—Energy Dispersive Spectroscopy (SEM-EDS). Viscosity and Vickers microhardness were also measured. It was found that the modification of amphibolite glass by adding dolomite affects the glasses’ properties and structure. The research results determined the effect of dolomite addition on the properties of alumino-silicate glasses in terms of the mineral fibre products used in the construction industry.

Basalt, known for its unique properties, is used for the production of yarns, fabrics, nets, and heat-insulating wool. Currently, a research is promoted on applicability of basalt as a dispersed filler for thermo- and rectoplastic materials without processing it into fibers. Therefore, investigation into interaction of epoxy binder with the crushed basalt is promising, which determines the aim of the given study. The objects of the research are the epoxy resin ED-20, polyethylene polyamine PEPA, and dispersed basalt filler. Spectrophotometer "Specord" with the IR-spectrum covering the area of 400 ÷ 4000 cm-1 was used to study the interaction of basalt filler with the epoxy oligomer and hardener. To take the photos of IR spectra of powders, the latter are pressed together with an excess of potassium bromide into tablets several millimeters thick. Special vacuum molds and pressure of several tons per 1 cm2 are used to produce the tablets. The ICS data confirm the interaction of ED-20 not only with PEPA, but also with the dispersed basalt. Amino groups, epoxy rings, CH groups of epoxy and aromatic rings of the binder and hardener undergo a reaction. As the content of the basalt filler in the epoxy increases, the same absorption maxima and bands are observed as in the IR spectra of the composite material with a low content of dispersed basalt. The difference is that the higher the basalt content in the epoxy matrix, the higher the relative intensity of such maxima, which indicates a stronger interaction of the components.
