Abstract
This preliminary study was conducted to establish the scientific basis for evaluating the structural performance of High-Strength Self-Compacting Concrete (HS-SCC) beams incorporating Waste Glass Powder (WGP) and Silica Fume (SF) as partial cement replacements. The study represents a continuation of previous material optimization research and serves as a transition toward the investigation of structural behavior at the reinforced concrete member level. A structured literature review was carried out using recent national and international publications related to SCC, HS-SCC, WGP, SF, shear behavior of reinforced concrete beams, and crack propagation mechanisms. The reviewed studies were synthesized to identify the relationships between material characteristics and structural performance parameters, including compressive strength, tensile strength, modulus of elasticity, first cracking load, load–deflection response, shear capacity, crack development, stiffness degradation, ductility, and failure modes. The review confirms that both WGP and SF have the potential to improve the mechanical properties and sustainability of HS-SCC when used within appropriate replacement ranges. However, most previous studies have focused primarily on material properties and flexural behavior, while investigations concerning shear behavior and crack propagation remain limited. The study identifies a significant research gap regarding the structural performance of HS-SCC beams incorporating WGP and SF, particularly in relation to shear resistance, diagonal crack propagation, stiffness degradation, and ductility under varying stirrup spacing and shear span-to-depth ratios. Therefore, further experimental studies are required to establish the relationship between optimized sustainable concrete materials and the structural behavior of reinforced concrete beams. The findings of this study provide a framework for future experimental investigations on shear performance and crack development in HS-SCC beams containing WGP and SF.
