Abstract

This invention relates to the field of building materials technology and discloses an optimization method for compensating shrinkage concrete that integrates the performance parameters of calcium-magnesium composite expansive agents. The method includes constructing a response model of the dynamic performance of key materials such as calcium-magnesium composite expansive agents and embedding it into a multi-stage coupled calculation model covering the construction period and long-term service life. A multi-objective collaborative inverse optimization algorithm is employed to obtain the optimal strategy, determine the optimal material mix and construction process, and generate a predicted state path for the construction process. During construction, a closed-loop active control system is deployed to monitor the structural state in real time and compare it with the predicted state path. Deviations are identified, and control commands are dynamically generated to correct the construction process, ensuring that the actual construction process precisely matches the optimal strategy. Completed project data is used for iterative model calibration, forming a closed-loop learning mechanism. This invention connects the design and construction stages, achieving data-driven active control and ensuring a high degree of consistency between the performance of the engineering entity and the design objectives.
