Abstract EN
This study investigated the basic mechanical and microscopic properties of cement produced with metakaolin and quantified the production of residual white efflorescence.
Cement mortar was produced at various replacement ratios of metakaolin (0, 5, 10, 15, 20, and 25% by weight of cement) and exposed to various environments.
Compressive strength and efflorescence quantify (using Matrix Laboratory image analysis and the curettage method), scanning electron microscopy, and X-ray diffraction analysis were reported in this study.
Specimens with metakaolin as a replacement for Portland cement present higher compressive strength and greater resistance to efflorescence; however, the addition of more than 20% metakaolin has a detrimental effect on strength and efflorescence.
This may be explained by the microstructure and hydration products.
The quantity of efflorescence determined using MATLAB image analysis is close to the result obtained using the curettage method.
The results demonstrate the best effectiveness of replacing Portland cement with metakaolin at a 15% replacement ratio by weight.
