INTEGRATED EXPERIMENTAL AND NUMERICAL STUDY OF HIGH-STRENGTH CONCRETE WITH SUPPLEMENTARY CEMENTITIOUS MATERIALS

Abstract

High-strength concrete (HSC) is widely used in modern infrastructure due to its superior mechanical properties and durability. The incorporation of mineral admixtures such as fly ash, ground granulated blast furnace slag (GGBS), and silica fume has proven effective in enhancing concrete performance while promoting sustainability. This study presents a comprehensive experimental and numerical investigation of high-strength concrete containing mineral admixtures. Experimental tests are conducted to evaluate compressive strength and durability characteristics. Numerical modeling is performed to validate experimental results and predict material behavior. The influence of different mineral admixtures on strength development is analyzed. Results indicate significant improvements in mechanical and durability properties compared to conventional concrete. The study demonstrates the reliability of numerical models in predicting high-strength concrete performance.
