초록

Since the void ratio of the form-block is relatively high, when the wall is constructed by using it, a lot of stress is transmitted through the filled concrete. Therefore, in this paper, in order to improve the performance of the grout concrete, the prism test of the form-block was carried out by using the steel fiber mixing ratio of the filled concrete as experimental variables. In addition, for the compressive strength of the form-block, prism strength from the experimental result was compared with the current design formula. Experimental results show that as the steel fiber content of the filled concrete increases, the phenomenon of abrupt drop of the flange after the maximum yield strength is delayed. The prism strength of the form-block can be predicted adequately by using the equation of Japanese standard as in the previous study. However, as the upper limit value of the mortar coefficient, it is appropriate to use 0.55 in consideration of safety in terms of design.
