Concrete Interface Feature Extraction and Stability Analysis Based on PCA Model

With the rise of concrete pumping construction technology, high-mobility has been more and widely used. However, high fluidity is prepared with sand ratio small stones, which weakens volume stability aggregate as a skeleton. Therefore, instability often appears in practical application large concrete. At present, research on interface feature extraction still relatively scarce. In this paper, through number experiments, law main performance systematically studied, characteristics are extracted using principal component analysis (PCA) model. On basis, influence different factors especially compressive strength, stability, durability The experimental results will have good reference value far-reaching significance for improving status
