Abstract
Coal ashes generated in a coal-fired power station are classified into two categories, clinker ash and fly ash. Among these two types of ashes, the number of utilized cases of clinker ash has been increased as a geomaterial such as embankment material, base course material, frost heaving restraint material and drainage material of ground due to its properties of light weight, high shear strength and high permeability. And also the application of clinker ash to vertical drain material, compaction pile material and tree planting matrix material on rock bed are studied at present. However, a study to identify material characteristics of clinker ash such as physical properties and mechanical properties is very little. From now on, increase of generation of coal ash and decrease of its dumping sites are surely so inevitable that utilization of coal ash to many fields have become a problem to be solved. On this account, in this paper, we report physical properties and mechanical properties of clinker ash and also the result that examined applicability as geomaterials.
