Determination of the Effective Calcium Content of Quicklime by Regression Analysis Using the Digestion Temperatures

This research involved randomly choosing 155 sets of experimental data that were collected from building companies. These sets of data were the result of lime analyses by sucrose titration done within 12 months by the laboratory attendants. The results of this experimental data were then gathered to be analyzed using the linear fitting formula. The results indicate that the analysis can accurately determine quicklime’s effective calcium content by regression analysis using the digestion temperatures. In addition, the X-ray diffraction method was used to test the quicklime’s calcium content, which verified that the method of linear fitting has good representativeness and practicability. This can greatly optimize the traditional process and has the prospect of being used widely.
