IMPORTANT DATA
Physical State; Appearance
LIGHT GREY OR WHITE POWDER. 

Physical dangers
 

Chemical dangers
Reacts with acids, aluminium metals and ammonium salts. Reacts slowly with water forming hardened hydrated compounds, releasing heat and producing a strong alkaline solution. 

Occupational exposure limits
TLV: 10mg/m³ as TWA; notice of intended change (see Notes).
MAK (inhalable fraction): 5 mg/m³; (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the skin and respiratory tract. The substance is corrosive to the eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: >1000°C
Density: 2.7-3.2 g/cm³
Solubility in water: reaction 
 

NOTES
The product is primarily a mixture of calcium silicates, aluminates, ferrites and calcium sulfate.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Sensitization observed with cement is mainly due to the presence of hexavalent chromium.
Some Portland cements may be free of hexavalent chromium.
In the presence of moisture, skin burns may occur 12 to 48 hours after exposure; there may be no pain at the time of exposure.
TLV Intended change1 mg/m³ (Respirable fraction) as TWA; (ACGIH 2008).
Card has been partially updated in February 2009: see Occupational Exposure Limits
