Innovative Methodological Approaches in the Study of Heat-Resistant Concrete

Abstract

article is dedicated to exploring methodological approaches used in the study of heat-resistant concrete. The research employed literature analysis, experimental testing methodology, and physico-mechanical tests to determine the properties of concrete under high-temperature conditions. Samples prepared using local raw materials (cement, gravel, sand) and heat-resistant additives (shungite, silicates) were tested at temperatures of 200°C, 500°C, and 800°C. The results indicated that as temperature increases, the compressive strength of concrete decreases (up to 57% at 800°C), while additives enhance its stability by 10-15%. Statistical analysis confirmed this correlation (p < 0.05). The article analyzes the advantages and limitations of methodological approaches and evaluates the potential for utilizing local resources in Uzbekistan. The research findings contribute to the adoption of sustainable and cost-effective materials in the construction industry.
