| Abstract: | Based on the principle and chaacteristics of idfrared testing technology, the inrared thermal image characteristic of fired cement mortar is researched by using infrared thermofraphy in the paper. The change curves of average rising temperature on infrard thermal image of cement mortar is obtained, and the regressive equations of average rising temperature of infrared thermal image to the fired temerature and the loss of strength of ordinary cement is established, and micro-structure of fired cement is analyzed. |
