Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
- Chemical name: Natural hydraulic lime
- Common name: Chaux Socli NHL 3,5
- Physical state: Grey powder
- Batch No.: XS 060110M1955
- Expiration date of the batch: 2010-07-30
- Storage condition of test material: Room temperature, in the dark

Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 450 °C
Remarks on result:
other: Significant thermal events did not occur. The unchanged residue appearance (grey powder) on completion of each determination confirmed that no phase transition of the test material had occurred during the heating up to 450 °C.

Applicant's summary and conclusion

Conclusions:
The melting point temperature of the test material has been determined to be greater than 450 °C.
