This paper presents a comprehensive study on the bond strength of concrete overlays incorporating industrial by-products such as fly ash and ground granulated blast furnace slag under high-temperature conditions. The research involved 540 concrete specimens exposed to temperatures of 25 °C, 100 °C, 300 °C, 500 °C, and 700 °C and cured for 14, 28, 60, and 90 days. Results demonstrated the beneficial roles of fly ash incorporation in overlays in improving the thermal stability and bond strength between concrete substrates and repair material overlays at high temperatures. Utilizing artificial intelligence techniques, a set of advanced machine learning models was created to accurately predict bond strength properties, specifically compressive, tensile, and shear strengths. The models evaluated included gradient boosting, extreme gradient boosting, light gradient boosting, and categorical boosting. Additionally, a multilayer perceptron (MLP) neural network was used as a baseline for comparison. The categorical boosting model demonstrated superior performance, achieving a root mean square error of 2.570, mean absolute error of 1.792, and R2 of 0.989 for predicting compressive strength in the test dataset. It also achieved similarly high accuracy for tensile and shear strength, with R2 values of 0.927 and 0.942, respectively. The SHapley Additive exPlanations analysis highlighted the significant impact of the predictive models on temperature, curing time, density, and porosity. Monte Carlo simulations further ensured robust model predictions and insights. The findings, accessible through a user-friendly web application (https://***/), provide valuable insights into optimizing material compositions and enhancing the durability of repaired concrete structures in extreme environments. This study demonstrates the efficiency and reliability of artificial intelligence in bond strength evaluation of heat-da

In this research, a novel rice composed of grated rice flour, whey protein, and lotus seedpod oligomeric procyanidins was developed through pre-gelatinization combined with twin-screw extrusion techniques. The nutritional, physicochemical properties and biological activities of the composite rice were systematically studied. Results revealed that the composite rice exhibited a 17.6% reduction in cooking time, a 23.6% increase in gelatinization degree, and a 51.8% decrease in rehydration water absorption compared to conventional rice. Meanwhile, compared to commercial rice, the composite rice showed superior elasticity, cohesiveness, chewability and resilience, alongside reduced hardness and viscosity. Notably, it displayed improved resistance to enzymatic digestion. Nutritionally, the contents of protein, fat, total phenol and proanthocyanidins were higher than those of commercial rice. Furthermore, it showed better antioxidant activity and advanced glycosylation end-products (AGEs) inhibitory activity. This research addresses the growing demand for nutritionally balanced rice products and advances innovative strategies for the application of composite raw materials in functional food development.
