Abstract
This research studies the development of lightweight concrete using unused alkaline binders as an environmentally sustainable alternative to traditional cement-based materials. The study highlights the environmental and economic benefits of this innovative approach, including reducing carbon dioxide emissions, energy saving, and efficient use of industrial emissions. Lightweight aggregates such as expanded clay and vermiculite were combined with alkaline binders such as sodium silicate and sodium hydroxide to produce concrete with excellent thermal insulation properties. From the results of the analysis, it became known to us that the density of the tiled sample materials ranged from 500 to 1200 kg/m3, the thermal conductivity coefficient from 0.12 to 0.25 W/M·K, and the compressibility strength was obtained in indicators in the range from 3 to 12 MPa. The above-mentioned properties make lightweight concrete one of the most alternative solutions for energy-efficient and insulating products. Widely used in construction, as well as the characteristics of consistency and compliance with long-term durability goals are discussed. The research work concludes with recommendations, emphasizing the need for research on long-term impact resistance and constructive structures.
