  • Respirable Crystalline Silica Dust Exposure During

    A total of 49 personal respirable dust samples were collected during concrete finishing while workers used hand-held grinders. Only 15 (31 ) of the grinders were equipped with local exhaust ventilation (LEV) systems. The confounding factors (e.g. wind velocity wind direction relative humidity and ambient temperature) were determined.

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
