ettringite (mineral, inorganic material, ... Materials (hierarchy name)) |
|
Note: A mineral composed of aluminum sulfate and hydrous basic calcium often formed by the reaction of sulfates and concrete or mortar. Ettringite crystal formation induces sulfate decay in the cement paste matrix. Conservation interventions seek to remove ettringite or limit its attack.

Additional Notes: |
|
| Dutch ..... Een mineraal dat bestaat uit aluminiumsulfaat en waterhoudende basische calciumverbindingen, en dat vaak ontstaat door de reactie van sulfaten met beton of mortel. Vorming van ettringietkristal wekt sulfaatverval op in de matrix van cementpasta. In conservering probeert men ettringiet te verwijderen of het effect van de aanvallen te beperken. |
