Effect of a CaO–SiO2–Al2O3 Composite Early-Strength Agent on the Early Mechanical Properties of Cement-Based Repair Materials

The early mechanical performance of cement-based repair materials is critical for the rapid rehabilitation of concrete structures and tunnel anchorage engineering. In this study, a reference mixture (ROA) without any accelerator, a general early-strength agent (GEA) based on aluminum sulfate, and a composite early-stre...

Synergistic Valorization of Ternary Industrial Solid Wastes for Sustainable Loess Stabilization: Mix Optimization, Strength Evolution, and Microstructural Mechanisms

This study investigates the mechanical properties and strength formation mechanism of loess solidified with a ternary blend of fly ash, lithium slag, and magnesium slag. The mix proportion was optimized using response surface methodology with a Box–Behnken design. Unconfined compressive strength (UCS) tests, digital im...

Rapid Abrasion-Resistance Prediction of Recycled Aggregates Using Improved Whale Optimization-Tuned Gaussian Process Regression and SHAP Analysis

High Friction Surface Treatment (HFST) relies heavily on wear-resistant aggregates to ensure roadway safety, yet the conventional evaluation of aggregate abrasion resistance is time-consuming and resource-intensive. In this study, a machine learning framework was developed to predict the abrasion-induced angularity evo...
