Study on Properties of Siberian Cocklebur Bionic Harmless Red Mud Modified Asphalt

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 22, 2025

ABSTRACT This study employed solid waste red mud (RM) as the primary material, which underwent dopamine self‐polymerization and esterification reactions to synthesize biomimetic composite materials based on Siberian cocklebur with high surface area (GA‐CDA‐RM). Experimental data indicate that GA‐CDA‐RM enhances high‐temperature rheological properties, rutting resistance, low‐temperature crack resistance of asphalt binder while reducing leaching heavy metal ions in RM. Leaching concentrations six metals decreased 10 μg/L, significant reductions four additional ions. At 46°C, binders modified a 4% mass fraction demonstrated substantial improvements: modulus ( G *) increased by 94.55% compared styrene–butadiene–styrene (SBS) (MA), both storage ′) loss ″) 96.99% 93.88%, respectively. 64°C 0.1 kPa, deformation recovery rate R ) GA‐CDA‐RM@MA improved 50.88% MA, at −12°C, m ‐value 14.8%. introduces novel approach for environmentally sound treatment reuse RM, providing guidance theoretical framework its recycling endeavors. It holds practical, environmental, reference value green sustainable pavement.

Comparative study on the effect of red mud acid leaching system and pure pharmaceutical system used for the preparation of Poly Aluminum Ferric Sulfate: performance and application

Research Square (Research Square), Год журнала: 2025, Номер unknown

The coordinated recovery of iron and aluminum from red mud for preparing inorganic polymeric flocculants constitutes a critical pathway to enhance mud's resource utilization value, yet the inhibition mechanism Na⁺ Si impurities generated during acid leaching process on flocculation performance remains unclear. This study therefore elucidates impurity-mediated regulation Poly Aluminum Ferric Sulfate (PAFS) structure-performance relationships through comparative synthesis pure reagent systems (PAFS-C) leachate (PAFS-J). Experimental results demonstrate that in PAFS-J, Na + occupies Fe/Al active sites via ion exchange inhibit hydroxyl bridging, while SiO2 calcined transforms into reactive silicic acid, fragmenting polymer structures Al-O-Si bonding Si-O-Si networks, leading significantly inferior efficiency compared PAFS-C. PAFS-J was further investigated Zeta potential analysis polarized light microscopy. relies electric double-layer compression weak charge neutralization form loose flocs, with its following multi-stage cooperative involving neutralization, adsorption-bridging, sweep flocculation. deeply elucidated mechanisms PAFS their mechanism, providing theoretical foundation precise design mud-based high-value industrial solid waste.
