Research on Clay-based Low-Carbon Building Materials in Ningbo: R&D, Process Improvement and Whole-Chain Innovation Model

Abstract

Based on Ningbo’s high-quality local clay resources, this research focuses on green inorganic new materials, low-carbon building materials, and the recycling of ancient building materials, constructing an innovative project that integrates material R&D, low-carbon production, green application, and rural industrial empowerment. Relying on traditional ancient brick-making craftsmanship, the research team improved the mud formula and optimized the low-carbon firing process, thereby enhancing the materials’ weather resistance and mechanical properties. Three product series were developed: low-carbon antique bricks, special bricks for ancient building restoration, and new green decorative materials. These products have been applied in the restoration of 86 cultural relics in Ningbo, including Tianyi Pavilion and Cicheng Ancient Building Complex, and have been expanded to green applications such as new Chinese-style buildings, low-carbon cultural tourism spaces, and photovoltaic supporting bases. The project constructs a closed loop integrating industry-university-research cooperation, green low-carbon practices, and rural revitalization. Through a linkage mechanism involving the government, enterprises, and villagers, it drives local employment and income growth, activating new momentum for rural revitalization. This paper systematically elaborates on the R&D and performance optimization of local clay-based low-carbon antique bricks, the low-carbon improvement path of ancient brick-making craftsmanship, and the whole-chain innovation model, providing a replicable industrial path for rural revitalization and ecological civilization construction.
