This study addresses the enhanced prevalence of carbonation, a process accelerating steel reinforcement corrosion, in recycled aggregate concrete (RAC) compared to natural concrete. Traditional carbonation depth assessment methods RAC are noted for being labor-intensive, costly, and requiring specialized expertise. There's deficiency application machine learning techniques accurately predicting RAC, gap this aims fill. Utilizing extreme gradient boosting (XGBoost) technique, recognized its efficacy ensemble learning, innovates modeling RAC. It emphasizes criticality hyperparameter optimization XGBoost algorithm maximizing model accuracy. To achieve this, three novel metaheuristic algorithms, including reptile search (RSA), Aquila optimizer (AO), arithmetic (AOA), were introduced as global optimizers tunning hyperparameters. The was underpinned by comprehensive database compiled from extensive literature, facilitating development an accurate model. Through rigorous evaluations, sensitivity analyses, Wilcoxon signed-rank test, runtime comparisons, synthesized models demonstrated exceptional accuracy, with coefficients determination exceeding 0.95. XGBoost-AO algorithm, particular, showcased superior performance, XGBoost-RSA providing efficient predictions considering runtime. SHapley Additive exPlanations (SHAP) interpretation highlighted environmental conditions significant influencers. A user-friendly graphical user interface developed, enhancing practical utility findings progression over time. research significantly advances predictive accuracy contributing sustainable management infrastructures emphasizing integration advanced structural engineering advancements.

Addressing the environmental threat of Polyethylene Terephthalate (PET) waste is critical for sustainable development. Despite PET's prevalence in everyday products, its improper disposal endangers health. This study targets a pivotal gap current research. PET waste's potential as building material will be thoroughly evaluated, focusing on whether recycling feasible. In construction industry, it can substitute natural sand and an additive cement. contributes to dual-purpose solution: mitigating pollution innovating science. The systematic literature review (SLR) delves into existing studies, impact concrete properties when substituting at ratios 5% 20% cement 0.5% 2% by weight. findings revealed that up 10% replacement enhances compressive strength, highlighting pathway practices. However, replacements above show reduction indicating optimal substitution threshold. Moreover, incorporating additives 1% weight optimizes flexural underscoring material's viability enhancing structural integrity. sheds light application reducing proposes viable, eco-friendly alternative materials. recommendation further research underscores necessity refine construction, aiming bridge knowledge encourage future innovations.
