Cement, portland, chemicals Use and Manufacturing

The majority of the cement used in construction is mixed with sand and gravel and water at a central plant and trucked wet to the construction site. Thus, there is little opportunity for exposure of workers at the site to cement dust. Nevertheless, many construction workers may be exposed to cement dust when small amounts are mixed on site or when cement or concrete materials are cut or ground.
