The amount of coal ash exhausted from the recent power plants has reached 1,200 tons every year in Japan. Coal ash is generally classified into two types; fly ash and clinker ash. Since the recycling of fly ash generally becomes popular, comparing the recycling of clinker ash, we tried to make sintered porous material from clinker ash effectively. However, it has not been clarified how physical properties and particle size of clinker ash powders affect the performance on use. In this study, we tried to produce two types of sintered porous materials with the clinker ash powders of different particle sizes and to measure their characteristics. As results, it was found that these clinker ash porous materials were enough suitable for water retention block, and also that the block produced by small particle powders showed higher evaporative performance.
