Abstract
This research delves into enhancing concrete strength through innovative approaches, particularly the substitution of traditional components with alternative materials like silica fumes, GGBS, fly ash, granite, and marble powder. The study specifically investigates the use of marble powder in self-compacting concrete, aiming to repurpose industry waste and minimize environmental impact. Focusing on M-40 concrete, the project replaces fine aggregate with varying proportions of marble powder (0%, 5%, 10%, 15%, 20%). The research explores the feasibility of this substitution by assessing the fresh and hardened properties, including self-compaction through tests like slump flow, V-funnel, and L-box. Additionally, beams are fabricated using TMT and HYBRID rods to evaluate structural behavior under diverse loading conditions. The experiment emphasizes the practical application of marble dust, considering its impact on flow properties and structural integrity. Multiple trial mixtures undergo testing, ensuring compliance with permissible limits for slump flow, V-funnel, and L-box. The structural behavior of beams, incorporating TMT and HYBRID bars, is thoroughly examined to ascertain the effectiveness of marble dust in enhancing concrete performance. In summary, this research offers valuable insights into the sustainable integration of marble powder in self-compacting concrete, addressing both environmental concerns and structural considerations.
