In this study, waste marble powder (WMP) was used to replace cement of concrete in specific amounts. To accomplish aim, WMP replaced at 10%, 20%, 30%, and 40% the weight, a reference sample without (REF) created compare compressive strength, splitting tensile flexural strength. The replacement weight resulted 5.7%, 21.7%, 38.1%, 43.6% decreases strength compared with REF. Furthermore, results commonly followed same trend as However, led 5.3%, 8.6%, 19.4%, 26.7% addition, three different calculations, ranging from simple complex, were proposed compute mechanical resistances WMP. These calculations for practical applications validated using values literature implications obtained current research. While based on REF percentages, complex dependent design mixture, age samples, percentages. For ANN approach help coefficient determination (R2) K-fold-cross validation method. All methods provided high accurate estimation predict properties Based studies, utilizing 10% is recommended obtain optimum benefits considering both environmental aspects. Moreover, scanning electron microscope (SEM) energy dispersive X-ray (EDX) analyses then conducted observe interaction concrete. According SEM analyses, some pores detected ITZ observed reaction zone. On other hand, EDX presence manifested by levels Calcium.

Marble powder (MP) and granite (GP) are disposed of primarily through landfilling, which leads to severe environmental issues. The utilization stone in cement-based materials offers a scalable disposal method. This paper begins by presenting the two powders' basic physicochemical micromorphological characteristics. Then effects mechanisms MP GP on hydration process microstructure concrete examined. Moreover, influences different substitution methods, water-cement ratio, other factors macro properties incorporating comprehensively summarized, bridging gap between microscopic changes induced addition macroscopic differences observed experiments. current state relevant technical standards is analyzed. Leveraging previous research results, we used machine learning techniques optimize mixture ratio with aim achieving comprehensive life cycle performance index. results reveal that fully exploiting fineness composition characteristics GP, along employing suitable mix design, powders exhibit filling nucleation accelerate cement hydration, refine pore structure, enhance workability, mechanical properties, durability concrete. Following proposed optimization substituting 16% can maintain standard strength 50 MPa while reducing carbon footprint 108.8 kg CO2e/m3 as well saving cost 284.8 yuan/m3. Review expected promote further applications waste achieve sustainable development.

The main objective of this work is to review the capability using waste marble dust (MD) particles as reinforcing materials in recycled polymeric composites achieve environmentally friendly materials. In present study, polymer were fabricated from polyethylene terephthalate (rPET) and MD then analyzed for their structural thermal properties. Preparation rPET-based containing 0–20 wt% was carried out through extrusion injection molding. For characterization Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), dynamic mechanical (DMA) applied. DSC revealed a nucleating effect on rPET, which manifested higher crystallization temperature (196.7 °C ⇒ 204.4 °C); however, also found hamper chain mobility, thereby decreasing crystallinity ratio (23.7 % 19.2 %) rPET altering its crystalline structure. According TGA measurements, slight increase occurred stability major decomposition increased 446 451 when 20 incorporated into it. DMA showed an improved stiffness entire investigated range MD-filled versus neat rPET. Additionally, several factors derived data, including effectiveness factor, degree entanglement, efficiency factor all suggested decent interaction between components indicating proper ability powder. However, above 5 content deteriorated due agglomeration filler particles, supported by electron microscopic images.

The escalating use of glass in an ever-evolving world poses a waste management challenge, with contributing to non-biodegradable landfill growth. Recycling emerges as viable solution, combating the need for additional landfills and environmental repercussions. This study employs scientometric content analysis from Scopus bibliometric database explores functional feasibility performance characteristics recycled (RGW) sustainable concrete production. Results indicate that Asia dominates research contributions RGW production compared other continents. Glass-mixed properties depend on type, particle size, shape, surface texture, replacement ratio, curing age. pozzolanic reactivity is correlated its relative fineness. Finer particles were considered more suitable due enhanced alkali-silica interaction. Utilizing powder fine aggregates improves mechanical properties, but high levels could affect strength development. Additionally, using RGA cement aggregate reduces concrete's thermal conductivity. not only aids understanding comprehensive overview incorporating into also identifies knowledge gaps, guiding development addressing challenges linked growing our contemporary society.
