Coal ash generated by coal-fired power plant has been effectively utilized as cement raw materials, concrete admixture and base course material. It is known that decrease in flow ability and hardening of coal ash is caused by moisture absorption and compression during transportation and storage, and could lead to blockage accidents of coal ash in hopper and pipe and so forth. In this paper, we investigated the effect of chemical compound for moisture absorption of coal ash. As the result, moisture absorption property of the coal ash depends on sampling points in the plant, and amount of moisture absorption is affected by soluble compounds in coal ash.
