Cement & Concrete Hazards In Construction

Concrete Burns • Sand contained in fresh concrete is abrasive to bare skin • Portland is an alkaline. Strong bases (ph of 12-13) are just as hazardous as strong acids to the skin but have no initial signs of pain such as a burning sensation. • Drying Portland is hygroscopic – it absorbs water. Portland needs water to harden.
