Cost-Efficient High-Performance Concrete: Evaluating Material Replacements for Economic Viability
摘要
The construction industry is increasingly focused on developing cost-effective and sustainable solutions for high-strength concrete that meet the demands for strength, durability, and overall performance. This review examines the use of alternative materials such as manufactured sand (M sand), Ground Granulated Blast Furnace Slag (GGBS), and silica fume as replacements for conventional ingredients in high-performance concrete production. The study investigates the effects of replacing fine aggregates with M sand and partially substituting cement with GGBS and silica fume on the mechanical properties, workability, durability, and cost-effectiveness of concrete [1]. The findings from various experimental studies highlight the potential of these alternative materials in reducing production costs while enhancing or maintaining strength, durability, and resistance to chemical attacks. In particular, the combination of M sand, GGBS, and silica fume results in improved long-term performance and environmental sustainability by reducing cement content and utilizing industrial by-products. The research suggests that these substitutions offer significant economic benefits, especially for large-scale infrastructure projects [2, 4]. This review contributes to the understanding of how such materials can support cost-effective, sustainable practices in concrete production while meeting the stringent performance criteria for high-strength concrete.
