In the short term, exposure to high levels of cement dust irritates the nose and throat. Longer term exposure could lead to occupational asthma. Mortar can also contain respirable crystalline silica (RCS). RCS is also found in concrete and can lead to the development of silicosis or scarring of the lungs, which results in a loss of lung
At central mixing plants, also known as "wet" plants, water is measured and added to the ready mixed concrete at the plant rather than in the field. This procedure was introduced to the industry for quality control and requires drivers to drop their loads within 90 minutes of leaving the plant.
