Results and discussion

Water solubility
Key result
Remarks on result:
not determinable because of methodological limitations
Details on results:
The test has been performed at 20±0.5 °C. For the preliminary test 0.1 g substance had been diluted with 100 ml water. The test showed that even after 96 h not all of the substance had been dissolved.

Applicant's summary and conclusion

Conclusions:
Interpretation of results: other: water unsoluble hydration products
Water solubility couldn’t be determined since the substance reacted with water. The hydration of the substance is intended. The substance is a new cement type, forming water unsoluble reaction products.
