INVESTIGATION OF PHYSICO-CHEMICAL PROPERTIES CHANKANAI DEPOSIT ZEOLITES FOR ENHANCED MODIFIED CONCRETE PRODUCTION

This study examines the physico-chemical properties of the Chankanai deposit zeolite and its potential as an additive in the production of modified concrete. The focus is on the investigation of the structural characteristics of zeolite, its chemical composition, and its modifying ability. Zeolites are aluminosilicate minerals with high adsorption capacity, and their use in building materials has the potential to enhance the strength, durability, and environmental friendliness of final products. X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods were applied to analyze the structure and morphology of zeolites. The XRD methods allowed for the determination of the crystal structure and phase composition of zeolite samples, revealing the presence of dominant mineral phases and their spatial arrangement. Using SEM, the microstructure and morphological features of zeolite particles were investigated, enabling an assessment of their porosity and distribution within the material. As a result of the experiments, it has been found that zeolites exhibit a high sorption capacity, well-developed porous structure, thermal stability, and resistance to chemical substances, making them promising raw materials for manufacturing cement composites, concrete, and other building materials. Additionally, the potential of enhancing the performance of these materials through the use of zeolites as well as the environmental and economic benefits associated with them have been discussed.
