The optimization and evaluation of 3D-printed polylactic acid (PLA) materials for reinforcing concrete elements present a promising avenue advancing sustainable construction methods. This study addresses the challenges associated with PLA’s dual nature—biodegradable yet mechanically limited long-term applications—while leveraging its potential to enhance reinforcement. research identifies gaps in understanding mechanical chemical behavior alkaline environments, particularly interactions matrices. To bridge this gap, four distinct PLA variants (high-impact PLA, engineering electrical ESD gypsum PLA) ABS (acrylonitrile butadiene styrene) were subjected dissolution tests NaOH solutions (pH 12 12.55) under three-point bending using digital image correlation (DIC) technology. Test specimens prepared optimized 3D printing strategies ensure structural consistency embedded beams analyze their reinforcement potential. Force–displacement data GOM ARAMIS measurements revealed significant differences responses, peak loads ranging from 0.812 kN 1.021 (electrical PLA). Notably, exhibited post-failure load-bearing capacity, highlighting capability. Chemical material-specific degradation patterns, high-impact Gypsum showing accelerated surface changes precipitation phenomena. Observations indicated white crystalline precipitates, likely lime (calcium hydroxide—Ca(OH)2), residue (sodium hydroxide—NaOH), or material-derived residues formed on near elements, suggesting interactions. These findings underline critical role material selection achieving effective PLA–concrete integration. While environmental sustainability aligns industry goals, reliability exposure remains challenge. concludes that demonstrates highest application reinforced concrete, provided stability is managed, as value (1.021 kN) showed 25.7% higher capacity than (0.812 did not lose any tests. work advances alternative construction, offering insights future innovations applications.

Geopolymers derived from bulk solid waste are considered ideal substitutes for cement-based materials in developing environmentally friendly construction materials. The utilization of tailings powder as a precursor alkali activation geopolymer can enhance the mechanical characteristics geopolymer. This study conducted extensive experimental studies on compressive strength, flexural SEM microstructure, thermogravimetric curve, and variable influence alkali-activated ilmenite (IT) mortar, using liquid-solid ratio number variables. An analysis was mortar's characteristics, machine-learning properties. Furthermore, impact different atomic ratios structure mortars also examined. test results revealed that metakaolin-iron titanium geopolymer, when doped with 10 % tailings, exhibited strength 72.30 MPa at 14 days. Similarly, reached 4.76 days 30 tailings. XRD showed Magnesiohornblende particles Mg-F-A-S-H C-A-S-H gel had positive negative correlations, respectively, doping level. TG indicated specimens exhibit enhanced thermal stability following treatment combining metakaolin formed Me-(F)-A-S-H gels. examination surface porosity, pore shape, unreacted material determined adding increased Si/Al Fe/Si ratios, enhancing transformation lamellar to three-dimensional disordered mesh structure. Additionally, contributed significant amount Ca, elevating Ca/Na (0.1−0.6) triggering calcium precipitation within Ca/Si range 0.03−0.2. increase led decrease sample's curing time extended. Based prior research application Gray Wolf optimization algorithm extreme learning, clear correlation identified between strength. increasing geopolymer's while an extended negatively correlated mixing deemed insignificant did not exceed 20 %. may derive environmental industrial benefits improvement their properties, stability, machine learning.
