Method for predicting concrete strength evolution in marine environment based on big data analysis

Abstract

The invention relates to a big data analysis-based concrete strength evolution prediction method in a marine environment, and comprises the following steps: (1) dividing 35 types of cement in different cement standards into five types of cement varieties by using a clustering analysis method, so that the problem that the cement varieties are complicated and numerous is effectively solved; (2) selecting mol / L as a unit for ion concentration values, and unifying ion concentrations in different experimental solutions and ion concentration values in a marine exposure environment; (3) determining that the wetting-drying cycle system of the tidal splash zone in the actual marine environment is greatly different from the wetting-drying cycle system of a laboratory. According to the invention, the method for fitting a tidal curve by using a cosine function is innovatively applied in the research, the tidal heights of different sea areas are recorded through an algorithm, and the cosine curve is fitted; and finally, the drying and wetting time is calculated, so the wetting and drying cycle system in the marine environment is obtained. After the data are processed, machine learning is carried out to predict the corrosion resistance of the concrete in the marine environment.
