Glass fiber reinforced mortar is used as a building material because of high strength. However, the effect of reinforcement of glass fiber is influenced easily by the manufacturing method. Moreover, some problems of the glass fiber reinforced mortar are described as follows. (1) Glass fiber reinforced mortar is inferior to other fiber reinforced cement mortar (FRC) in the long term durability. (2) Drying shrinkage rate is large. (3) The mortar is inferior to other FRC in thermal resistance. Authors have studied on fly ash fiber reinforced mortar produced by fusing coal ash. As a result, fly ash fiber reinforced mortar is excellent in the long term durability and heat resistance, drying shrinkage rate is small. Authors proposed the method of improving the performance of glass fiber reinforced mortar. The method is combining fly ash fiber to glass fiber. As a result of the test, it was confirmed that strength of glass fiber reinforced mortar increased, and that durability and thermal resistance improved.
