| Abstract: | Physical-chemical properties of ash discharged from Guiyang thermal power plant and its influence upon physical-chemical properties of clay were studied. The results showed that the coal ash is a comprehensive grain, It has porous, light, sandy and basic characteristic, and contains trace elements for plants. Therefore,it has effect of improvement on clay, and is a good material for the improvement of Guizhou acid yellow clay. |
