Mechanical Property of Coal Ash Mixed with Clay

The shear strength of coal ash mixed with the 30% clay content is nearly equal to that of pure coal ash. With the increase of clay content, the coefficients of compressibility a1-2 have a little irregularly growth. It always belongs to medium compressibility soils.


The American Coal Ash Association (ACAA) (ACAA 2007) estimates that during 2006, the U.S. utility industry generated 16.9 million metric tons (18.6 million tons) of bottom ash and 1.8 million metric tons (2.0 million tons) of boiler slag.
