The primary purpose of this study is to hvestigate reusal techniques of high calclun-i fly ash in the construct.ion field, which may contribute to the savings of construction materials and consenratlng environment. Furt.hcrrnore, it can setup material properties or characteristics requiremi for development of new materials. Firstly, chemical and physical cahraci.eristics of liigh~calciurn fly ash is arialyseti. And then, the usability of the concrete is tcsted by investigating the flowablility and strength development through parameters of various replace ment r,itios with respect to different nuxing conditions. Finally, the durability and mechanical properties(e1astic nlodulus of the concrete is tested. As the result of the study, the following conclusions are derived : (1) the quaritii y of the CaO The primary purpose of this study is to hvestigate reusal techniques of high calclun-i fly ash in the co:lstruct.ion field, which may contribute to the savings of construction materials and consenratlng environment.
