Synopsis
High strength fiber reinforced mortar was developed and its applicability for towers and low height bridge girders was stupid. Various material experiments and the loading experiments of tower and girder specimens were conducted. As a result, it showed that it is possible to construct the towers and low height bridge girders by high strength fiber reinforced mortar. High strength fiber reinforced mortar was already applied to the low height bridge girders and towers. In addition, it can be economically applied to the prestressed concrete structures whereas ordinary concrete cannot be adopted.
