Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 285-561-1 | CAS number: 85117-09-5 Mixtures of chemical substances produced by burning (below 1200°C) natural variants of limestone or chalk containing from 10 to 20%, or more, of clayey or siliceous materials which are predominantly SiO2, Al2O3 and iron oxide. Consist primarily of 2CaOsb.2, Ca(OH)2, CaO and 2CaOsb.2O3. 3CaO.2SiO2, 4CaOsb.2O3. Fe2O3, 2CaOsb.2O3sb.2, CaCO3 and SiO2 may also be included.
Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-03-05 to 2010-05-21
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP guideline study reliable without restrictions
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- , 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 2009-11-26
- Type of method:
- air comparison pycnometer (for solids)
- Type:
- relative density
- Density:
- 2.7
- Temp.:
- 22
- Remarks on result:
- other: Variation of temperature was ± 0.5 °C.
- Conclusions:
- The relative density of the test material has been determined to be 2.70 at 22.0 ± 0.5 °C. The deviation from the nominal temperature (20 °C) does not significantly affect the accuracy of the density value.
Reference
Description of key information
Relative density (compared to water at 4 °C) is D4R= 2.70 (22.0 °C) (study result, EU A.3 method). The deviation from the nominal temperature (20 °C) does not significantly affect the accuracy of the density value.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.7
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
