Abstract
Recently, some methods to utilize the coal ash, that occurs as a waste product of thermal power plant operation, have been investigated. Fly ash fiber, that is produced by fusing coal ash and at high temperature and pulling it into fibers, exhibits high strength, thermal resistance and alkali-proof. Therefore, it was thought that if fly ash fiber could be used in the making of reinforced mortar, precast products of high strength, thermal resistance and durability would result. This report describes test results on the mechanical properties of fly ash fiber reinforced mortar. As a result, it was confirmed that the fly ash fiber reinforce mortar maintained excellent workability, high flexural strength and thermal resistance.
