Concrete carbonization depth prediction method based on MATLAB and COMSOL

Abstract

The present application relates to the technical field of concrete carbonization depth prediction, and in particular to a concrete carbonization depth prediction method based on MATLAB and COMSOL. The method includes: obtaining the working condition data of concrete and the experimental carbonization depth of concrete; inputting the working condition data into the concrete carbonization simulation model to obtain the cross-sectional CO2 concentration distribution diagram of the concrete at any time; the concrete carbonization simulation model is a model constructed by MATLAB and COMSOL, which inputs material transfer parameters and outputs the CO2 concentration distribution model in the concrete; according to the experimental carbonization depth and the cross-sectional CO2 concentration distribution diagram, the target CO2 concentration is obtained; according to the target CO2 concentration and the cross-sectional CO2 concentration distribution diagram, the carbonization depth interval of the concrete at any time is predicted, avoiding the problem of being unable to accurately simulate the process of CO2 diffusion in concrete and completing the carbonization reaction.
