“…If these wastes are not properly treated, they will exert significant pressure on the environment. However, if the resources contained in these wastes are properly recycled and reused, not only can the environmental burden be reduced, but also new resource channels can be provided for the construction materials industry [3][4][5]. Against this backdrop, transforming building solid waste into recycled concrete has become an important technical route.…”

With the acceleration of urbanization, the amount of construction solid waste has increased dramatically. How to effectively deal with and utilize these wastes has become a major challenge in environmental management and resource recycling. Transforming these wastes into recycled concrete is a feasible way to solve this problem, where the thermal stability of concrete is a key attribute to ensure its structural safety. This study, based on thermodynamic principles, delves into the thermal stability of building solid waste recycled concrete. Firstly, the multiphase heat conduction behavior of recycled concrete is analyzed, and a thermodynamic model is used to simulate the heat exchange process between different phases; secondly, through the grey relational analysis method, the thermal stability performance of recycled concrete under different conditions is comprehensively evaluated. Previous studies mostly relied on simplified physical models or empirical formulas to predict the thermal stability of recycled concrete, which cannot fully reflect the impact of the material's microstructure and complexity on its thermal behavior. To overcome these shortcomings, this study proposes a new method combining multiphase heat conduction analysis with grey relational evaluation, aiming to provide a more accurate and practical model for predicting thermal stability. The research results verify that the proposed method can effectively reveal the contribution of each constituent phase to the thermal stability in recycled concrete, which is of great significance for the realization of high-performance, sustainable recycled concrete material design.

“…Many academics have previously studied the topic of recycling construction solid waste (hereinafter referred to as solid waste). China and the United States have made exceptional contributions in this area [14] and have investigated a variety of recycling techniques for it. In place of natural aggregate resources, recycled aggregates from construction solid waste are added to cement and concrete [15][16][17][18][19].…”

Environmental problems including the depletion of natural resources and energy have drawn a lot of attention from all sectors of society in the context of high-quality global development, and solid waste generated by the construction industry accounts for 36% of the total amount of municipal waste. The generation of large amounts of construction waste not only causes a waste of resources, but also causes great damage to the environment. Reducing the quantity of solid waste produced during a building’s new construction period can be greatly aided by construction site solid waste statistics and forecasts. Based on the statistical data of 61 public construction projects in Hainan Province, China, this study uses the Random Forest algorithm to rank the importance of possible factors affecting the amount of solid waste generated, and linearly fits the data to achieve the prediction of solid waste at construction sites. The findings indicate that, building area, building height, concrete usage, steel usage, and assembly rate are the main factors affecting solid waste in construction sites. In office buildings and exhibition buildings, an increase in ground area, building height, concrete usage, and steel usage increases the generation of each type of solid waste (inorganic non-metallic solid waste, metallic solid waste), with the exception of an increase in concrete usage, which results in a decrease in the generation of metallic solid waste. Furthermore, a higher assembly rate can substantially lower the production of all waste types. These results offer a theoretical foundation for the implementation of assembly construction to support the high-quality development of the construction industry, as well as partial design inspiration for the architectural design stage.
