Influence of Metakaolin on the Efflorescence of Cement-Based Composites Using Matlab Image Analysis


Article Preview

The studying used different metakaolin replacement ratio of cement mortar exposed to different environments to investigate the quality of cement with metakaolin basic mechanical properties of materials and white efflorescence quantify the effect of microscopic properties. The specimens were analyzed with Compressive strength test and Matlab image analysis. The results presented that: (1) Comparing with between the appropriate amount of metakaolin replacement of cement and control group, the compressive strength of the appropriate amount of metakaolin replacement of cement is higher than control group’s. Especially, the compressive strength of 15% metakaolin replacement of cement is the highest; (2) Matlab image analysis the amount found in white efflorescence into freezers > carbon tube ≒ normal atmosphere.
