Coal ash which is by-products of coal thermal power plant(CTPP) is produced by 15~45 % of resource coal.
In domestic, production amount is about 2 million ton a tear from current capacity and 5 million ton a year is expected in 2001.
The coal ash, which is general industrial waste materials, requires a great deal of disposal expenses and causes a number of problems.
Therefore many countries force on the research for utilization of FLY ASH.
CTPP is being increased and in future a great amount of coal ash will be produced be operating the large bituminous CTPP.
Therefore, researchs for the coal ash utilization in various fields are required as soon as possible.
Based on the needs mentioned above, the primary objective of the study is to debelop a methodology for the utilization of FLY ASH as a mineral admixture in concrete, by which a reduction of the construction material and treatment cost would be expected.
In addtion, environmental conservation and improvement of concrete quality could also be achived.
