The presented article describeds the results of scientific research on the use of waste glass in concrete production. In accordance with the research topic, it was studied that glass waste can be used as fine and coarse aggregate in concrete production and its feasibility as a sand substitute was confirmed. According to the topic, glass cullet was replaced in concrete material in the amount of 20%, 40% and 60% of the sand raw material, and the technological, physical and mechanical properties of the resulting samples were evaluated through tests. Based on traditional concrete production, samples were prepared and stored in a standard environment for hardening. Thus, density tests along with slumping are carried out for fresh concrete and, at the same time, analyses are carried out to determine the compressive strength, resistance to impact, and water absorption capacity for the hardened finished sample.
According to the research topic, the application of 40% glass cullet as a sand substitute has a positive effect on the mechanical and physical properties of concrete. However, at 60% substitution, the adhesion of the mixed cement raw material in the interfacial layer decreases, and as a result, the indicative values of the mechanical properties of the product weaken. According to the scientific research, the use of glass waste as a sand substitute was considered more efficient and expedient from both ecological and economic points of view.

SYNTESIS AND PROPERTIES OF Ti-Si CATALYSTS FOR THE SELECTIVE OXIDATION OF ALKENES TO KETONES WITH HYDROGEN PEROXIDE

This study investigates heterogeneous Ti–Si-based catalysts for the selective oxidation of organic compounds using hydrogen peroxide as a green oxidizing agent. The catalysts were synthesized via a hydrothermal sol–gel method, with carefully controlled conditions to ensure the effective incorporation of titanium species into the silica matrix, forming a highly ordered porous framework. A range of characterization techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS), nitrogen adsorption–desorption (BET), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), was employed to analyze the physicochemical and structural properties of the materials.
