ULTRASTRENGTH CONCRETE: HYBRID STUDY OF STRUCTURAL BEHAVIOR WITH MINERAL ADMIXTURES

Abstract

High-strength concrete (HSC) is increasingly used in modern structural systems due to its superior load-carrying capacity and durability. The incorporation of mineral admixtures such as fly ash, ground granulated blast furnace slag (GGBS), and silica fume further enhances structural performance and sustainability. This paper presents a hybrid experimental– numerical assessment of the structural behavior of high-strength concrete containing mineral admixtures. Experimental investigations are carried out to evaluate load capacity, stress–strain behavior, and cracking characteristics. Numerical modeling is performed to simulate structural response and validate experimental results. A comparative evaluation between experimental and numerical outcomes is conducted. The results show close agreement, demonstrating the reliability of the numerical approach. The study confirms that mineral admixtures significantly improve the structural efficiency of high-strength concrete.
