With cement solutions infiltration the swelling pressures increase sharply reaching the first peak at 10 and 75 h at 20 and 60 °C respectively For the two cement solutions the value of swelling pressures at the first peak is the same at a given temperature in Table 3 It demonstrates that the effect of chemistry of pore water on
Controversy exists as to the role exposure to dust has in the development of chronic bronchitis inflammation of the air passages into the lungs Other factors such as smoking and general air pollution are more important but dust exposure may contribute 4 May cause silicosis and pneumoconiosis
Bentonite Powder The term Bentonite was first used for a clay found in about 1890 in upper cretaceous tuff near Fort Benton Montana The main constituent which is the determinant factor in the clay''s properties is the clay mineral montmorillonite
Bentonite when exposed to liquid thickens and forms a gel or paste according to the Industrial Minerals Association of North America This same thickening ability makes it an effective lubricant in diaphragm walls foundations and in tunneling and drilling operations It is also used in cement mortars and in Portland cement
