PORTLAND CEMENT ICSC: 1425
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
LIGHT GREY OR WHITE POWDER.

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: (particulate matter containing no asbestos and <1% crystalline silica) 10 mg/m (ACGIH 2001).
MAK: I, 5 mg/m (DFG 2000).
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 the 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
Melting point: >1000C
Density: 2.7-3.2 g/cm^3
Solubility in water: reaction
ENVIRONMENTAL DATA

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.
