Embodiment
[0053] The present embodiment illustrates the method of the present invention with cement slurry. Specific steps are as follows:
[0054] a) Use PI52.5 cement to form a cement slurry sample in a PU pipe with Φ=8.2mm and L=50mm, and put it in a saturated calcium hydroxide solution for curing for 8 months at a curing temperature of T=20±2°C;
[0055] b) Cut and polish the sample into a cylindrical sample with Φ=8.2mm and L=10mm;
[0056] c) adopt vacuum saturated water method, carry out vacuum saturated calcium hydroxide solution treatment to sample;
[0057] d) performing X-ray tomography on the sample to obtain a set of initial two-dimensional images IO of the sample before freezing and thawing;
[0058] e) Using the vacuum saturated water method, the sample is again treated with a vacuum saturated calcium hydroxide solution.
[0059] f) Freezing-thawing pretreatment of samples: immerse a part of the samples in aviation kerosene, coded as sample 1; fully seal a part of the ...
