Core Viewpoint - The innovative technology for high-value recycling of waste concrete developed by Nanjing University of Technology addresses the challenge of achieving carbon neutrality by enhancing the performance of recycled concrete materials in structural engineering [1][2]. Group 1: Technological Innovations - The research team led by Associate Professor Xu Jinjun has created an automated washing and screening equipment for recycled aggregates, significantly improving the physical properties of recycled coarse aggregates [1]. - The new pre-treatment process for recycled fine aggregates involves a combination of calcium hydroxide soaking and carbon dioxide curing, resulting in an increase in apparent density by 1.8% to 4.8% and a reduction in crushing rate by 20.2% to 23.5% compared to traditional methods [1]. Group 2: Performance Optimization - The team has optimized the mix design of recycled concrete to address the challenges of achieving the right consistency, utilizing methods such as the equivalent mortar volume method and the equivalent total water method to enhance mechanical strength while reducing water usage [1][2]. - A database has been established to record the performance of recycled concrete under various environmental conditions, allowing for precise calculations of the optimal mix ratios of cement, water, sand, and recycled aggregates [2]. Group 3: Structural Enhancements - The team has innovatively integrated internal steel and external steel casing into the structure of recycled concrete, enhancing its stability and safety [2].
