Cement Concrete Strength Quality Evaluation by Dynamic Time Series Features

Cement concrete strength quality is tested by the standard testing methods and the historic test results always documented in the formatted formal reports. They are difficult to gear for quality data analysis from multi-dimensional. Firstly, according to data engineering, the data attributes refer to time and strength quality in original cement concrete test reports are defined, extracted and preprocessed; Secondly, by time sliding windows the historic strength test data are divided into dynamic time periods and the features of mean, variation, median, coefficient of variation, mode, and full distance are constructed during every time period. Finally, the detailed evaluation results of cement concrete strength quality are provided by integrating the multi-features of multi-periods. Experimental results show that the raw data are defined and preprocessed to be less redundancy and reliable by data engineering and the integrated evaluation results become more accuracy and effective by the dynamic time series features.
