Outline of Final Research Achievements |
Polymer cement mortar (PCM) method that uses lattices of the reinforced fibers such as the carbon and the glass bar arrangements (FRP lattice muscle) and composite materials (HPFRCC) method composed by mortar and the short fiber for reinforcement were thought as a reasonable reinforcement of the irrigation canal tunnel with the cementitious material. It was important to consider the balance of the reinforcement level and the bond strength when these methods were designed, and it was clarified to be able to decide the reinforcement level by setting the allowed amount of displacement and the width of the crack. Moreover, it proposed the new examination method that examined the bond strength, and the impregnation method that was able to improve the bond strength clarified that it was important to note the combination of the impregnation material and PCM.
