The purpose of the study is to show the possibility of using high-tonnage waste from the chemical industry in the production of building materials. Methods and materials. Methods of data comparison and analysis were used. Solid residues of distiller sludge with a moisture content of 25-30%, an active calcium oxide content of 12-13% and quartz sand with a grain size of 2.2, humidity of 5-6% were used as materials. Results. Compositions and methods for obtaining a cement-free binder based on the solid residue of soda and quartz sand production are proposed. The possibility of obtaining a binder based on the solid residue of distiller slurries according to two technological schemes: drying of the solid residue and grinding together with quartz sand; firing of the solid residue and grinding together with quartz sand, has been confirmed by our tests. The introduced concept of “Eco-friendly hybrid cements” (Eco-friendly hybrid binders (EHB)) emphasizes that they are binders made up of multicomponent mineral raw materials of secondary resources. Practical significance. Solid by-products of the chemical industry can be used as an auxiliary inorganic component. This will make it possible to create eco-friendly hybrid cements ready for use, which are sealed only with water, which contributes to the development of such binders by industry and the rational use of secondary mineral resources.

The use of waste materials in alkali-activated material technologies is important in terms of sustainability. The production of alkali-activated composites (AAC) with hollow brick waste (HBW) as a binder may contribute to solving existing environmental problems related to the depletion of natural resources. In this study, mortars were produced using different concentrations (6 M, 8 M, and 10 M NaOH) and Alkaline Activator/Powder Material (AA/PM) ratios of 0.30, 0.35, and 0.40 through the alkali activation method. The hollow brick waste (HBW) powder was obtained by grinding inactive bricks in brick factories. The prepared mortars were cured separately for each mixture at 90°C for 24 hours. Compressive and flexural strength tests were performed on the prepared perforated hollow brick waste-based composites. The Taguchi method was used to determine the optimum mixing ratios by conducting compressive and flexural strength tests on the produced AAC. To optimize the parameters determined using the Taguchi method, the best mixing ratios were determined using the L9 (3^2) orthogonal index. The compressive and flexural strengths of the mixtures were evaluated considering the signal to noise ratio "larger the better" and the highest compressive strength value was 63.669 MPa and the highest flexural strength value was 6.629 MPa according to the optimum values. According to the obtained results, it was determined that the AAC produced at 6 M NaOH and 0.30 AA/PM ratio exhibited the highest compressive and flexural strength values.
