Synergistic Regulation of Waste Glass Powder and Aggregate Packing Structure for Sustainable Cement Mortar: Microstructural Mechanisms and XGBoost-PSO Intelligent Mix Design Optimization

Waste glass powder (WGP) is a promising recycled constituent for sustainable cementitious materials, yet its effectiveness depends strongly on the packing characteristics of the fine-aggregate skeleton. This study investigates the coupled effects of WGP replacement ratio and fine-aggregate gradation on the mechanical p...

Machine Learning for Concrete Performance Prediction and Intelligent Optimization: A Comprehensive Review

Comparison analysis indicates that ensemble tree-based models—particularly random forest and gradient-boosting variants such as XGBoost—together with well-tuned neural networks consistently achieve the highest predictive accuracy across most concrete properties, whereas limited data availability, inconsistent validatio...
