Abstract
In the field of civil engineering, grouting materials are widely used in repair and reinforcement engineering, and their durability and long-term stability are key to ensuring the long-term safe operation of the project. This study first outlines the basic properties of grouting materials, including their types, physical and chemical properties, and then delves into the theoretical factors that affect the durability and long-term stability of grouting materials. This study systematically analyzes how material composition, construction technology, environmental factors, and design and structural factors affect the durability of materials through theoretical analysis and experimental research. This study proposes strategies to improve the durability and stability of grouting materials, covering aspects such as selecting optimal materials and scientific ratios, strictly controlling the construction process, environmental and corrosion control, and structural design and load management. The research background and significance section emphasizes that in the current context of rapid development in the construction industry, improving the durability and stability of grouting materials is of great significance for extending project life and reducing maintenance costs. The current research status at home and abroad points out that although progress has been made in durability and stability research, there are still research gaps, especially in the accumulation of long-term performance data and the durability research of composite materials in complex environments. The research results of this article not only provide scientific material selection and usage suggestions for engineering practice, but also provide scientific support for the formulation of relevant standards and specifications, which is of great significance for promoting technological progress and industry development in the field of civil engineering.
