“…Because the existing literature has indicated that these percentages may be used without substantial reduction, the high percentages of 25% and 35% were chosen [40][41][42][43][44]. In order to assess the economic viability of this substitution, the physical behaviour of the new concrete was compared to the cost [45].…”

<p>Concrete is an indispensable construction material renowned for its versatility and durability, yet its traditional components pose significant environmental challenges. The cement industry is a major emitter of CO2, while the extensive extraction of natural aggregates depletes finite resources. In response, researchers have explored alternative materials like Marble Waste Powder (MWP) as sustainable substitutes in concrete production. This study investigates the feasibility of incorporating MWP as partial replacements for cement and fine aggregate, examining substitution fractions of 25% and 35%. Through experimental analysis, the mechanical properties and cost implications of these modified concrete blends are evaluated. The research findings reveal that integrating MWP into concrete formulations enables the production of high-strength concrete at a reduced cost, offering a promising solution to enhance the sustainability of construction practices. By partially replacing conventional materials with MWP, the environmental impact associated with concrete production can be mitigated, contributing to efforts aimed at reducing carbon emissions and conserving natural resources. Additionally, the study underscores the importance of eco-friendly innovations in construction materials, emphasizing the need for sustainable alternatives to meet the growing demand for infrastructure development while minimizing environmental harm. Overall, this research highlights the novel use of MWP as a sustainable alternative in concrete production, showcasing its potential to address environmental concerns and promote more eco-conscious construction practices. Through the exploration of mechanical performance and economic feasibility, the study provides valuable insights for advancing sustainability in the construction industry and achieving long-term environmental stewardship.</p>

This study evaluates the performance of PVCC (Polyvinyl Alcohol Cementitious Composite) layered beams (BP1 to BP5), basalt fiber fabric-wrapped beams (BB1 and BB2), and a control beam (B0). Results show that specimen BP3, with 1.2% PVA fiber in PVCC layered beam, and BB2, with basalt fiber fabric wrapped at the bottom up to the neutral axis, exhibit superior performance. BP3 delays first crack initiation, increases the ultimate load-carrying capacity by 19.87%, and achieves a remarkable 54.57% increase in maximum ductility compared to B0. BP3 also demonstrates 54.54% higher stiffness and notable energy absorption. Similarly, BB2 outperforms BB1 and B0 in first crack load, ultimate load carrying capacity, ductility, stiffness, energy absorption, and energy index. BB2 exhibits 2.10 times increase in ductility compared to B0. Incorporating PVA fiber in PVCC layered beams and basalt fiber fabric wrapping offers better improvements in crack resistance, load capacity, ductility, stiffness, and energy absorption, contributing to innovative and sustainable beam design in construction.

This experimental research evaluates the structural performance of laced reinforced concrete beams in comparison to conventional reinforced concrete beams (RC-90) under reverse cyclic loading. Visual inspection revealed that LRC-45 exhibited superior crack resistance, even at high displacements, unlike RC-90, which displayed vertical cleavages and diagonal tension cracks. RC-90 demonstrated minimal ductility, initiating cracking at lower loads. Hysteresis response curves showed LRC-45 outperforming RC-90 in terms of cracking load and maximum load, with higher displacement capacity. The ductility factor of LRC-45 was 56.39% higher. Notably, LRC-45 exhibited a substantial 143.43% increase in cumulative energy dissipation, highlighting its superior energy-absorbing capacity. Additionally, stiffness analysis indicated significantly higher stiffness in LRC-45. The numerical analysis supported experimental findings, emphasizing the potential of laced reinforcement in enhancing structural resilience, energy dissipation, and stiffness. The novelty lies in the remarkable improvements offered by LRC-45, particularly its enhanced energy-absorbing capacity and stiffness, which are crucial for structures subjected to dynamic loads, such as seismic events.
