18.Research on Multifunctional Intelligent Concrete: Landing Barriers and Industrial Path from Laboratory Samples to Structural Intelligent Carriers

1. Frontier Research Status of Intelligent Concrete
At present, global scientific research institutions have made phased progress in the research of multifunctional intelligent concrete. By doping conductive carbon materials, metal powders and functional composite fillers, concrete has intelligent characteristics such as stress sensing, temperature perception and deformation self-monitoring. Energy-storage concrete can realize building energy storage and peak load regulation, and self-monitoring concrete can feed back structural stress changes in real time. A variety of functional intelligent concrete samples have completed performance verification in the laboratory, realizing the integration of building bearing and intelligent sensing functions.

2. Core Industrial Transformation Barriers
Although the laboratory technology is advanced, the large-scale engineering application of intelligent concrete still faces multiple barriers. First, the cost of functional modified materials is high, resulting in excessive comprehensive cost of intelligent concrete, which is difficult to popularize in ordinary projects. Second, the long-term functional stability is insufficient, and the sensing accuracy is easy to attenuate with the extension of service time. Third, the industry lacks unified design specifications, construction standards and performance evaluation systems, resulting in no basis for engineering application and acceptance, which seriously restricts the industrial transformation of achievements.

3. Phased Future Landing Path
The industrialization of intelligent concrete will adopt a gradual promotion strategy from local components to main structures. In the initial stage, it is applied in key monitoring components such as building foundation, bridge key sections and tunnel lining to realize structural safety real-time monitoring. With the continuous optimization of cost and stability, it will be gradually popularized in building floors, energy storage floors and other functional structural parts. In the long run, realize the full coverage of intelligent concrete in intelligent buildings and smart infrastructure, and build a new generation of self-perceiving and self-monitoring building structure system.

4. International R&D Cooperation Layout
Enterprises can carry out joint experimental research with overseas universities and scientific research institutions to jointly tackle the problems of functional stability and cost reduction of intelligent concrete. Participate in the formulation of international industry standards for intelligent building materials, break international technical barriers. Form export-oriented intelligent concrete sample products and technical solutions, and seize the commanding height of global intelligent building material technology research and development and industrial development.

Conclusion

Multifunctional intelligent concrete represents the intelligent development direction of future building materials. Breaking through cost, stability and standard barriers will accelerate its transformation from laboratory research to engineering application. Phased promotion and international standard layout will help domestic intelligent concrete technology take the lead in global industrial competition.
