DEVELOPMENT OF CEMENT MIXTURE MATERIAL BY FINE PULVERIZING OF COAL ASH

Abstract

As a substitute for the Shirica fume which is widely used as a high flow and high strength concrete mixture material, a new mixture material was developed from the coal ash waste of the thermal power stations.
A fine powder of coal ash was produced by mechanical pulverization with an addition of strength improvement materials, and the fresh properties, dynamic characteristic, and other characteristics of the concrete containing our new mixture material were examined.
As a result, it was confirmed that our material is easy-handling and also has a strength appearance equal to Shirica fume.
