    Abstract: A method for predicting and calculating aggregate surface energy is provided and includes steps: (1) raw aggregate screening and treatment; (2) surface texture index acquirement of a polished aggregate and an untreated raw aggregate; (3) powdered aggregate testing by a capillary rise method; (4) polished aggregate testing by a sessile drop method; (5) function relationship formula fitting; and (6) surface energy calculation of raw aggregate. The method not only considers the influence of aggregate's own composition on the surface energy, but also considers the influence of the polishing treatment on the aggregate surface texture, analyzes actual surface texture conditions of the aggregate, and significantly improves the test accuracy by combining the sessile drop method and the capillary rise method. Moreover, it can replace vapor adsorption method to test the surface energy of aggregate, which greatly reduces the test cost and operation difficulty.

  • Patent number: 11503472
    Abstract: A mobile device collects received information and processes it. In some instances, the mobile device detects, based on the collected information, that a base station is likely not legitimate, i.e., it is likely a fake base station, and the mobile device bars communication with the base station for a time. In some embodiments, the mobile device determines, based on the received information, that the base station is a genuine base station. When the mobile device determines that the base station is a genuine base station or the mobile device does not determine that it is likely the base station is a fake base station, the mobile device allows or continues communication with the base station.
