초록

Recently, a research related to development of form-block has been performed to improve the effectiveness in both construction of new building and retrofit of old building. From several previous prism tests on the form-block wall (FBW), it has been revealed that the concrete filled in the void of the form-block expands to horizontal direction when the compressive load increases and the failure of FBW at ultimate load is governed by the shear failure of web of form-block. This failure brings on weak resistance of wall. In this manner, this paper aimed to verify the compressive strength of the form-block reinforced with steel fiber through both compressive and prism test on the block. In addition, the suitability of previous equation to predict the prism strength of form-block is evaluated. Main parameters in the experiment are type of steel fiber, strength of grout and mortar, and strength of base mortar. As a result, the compressive strength of block and prism strength were improved by adding 1% of steel fiber into block. The ductility of block with steel fiber was improved but was not in prism test. The prism strength of the form-block wall can be properly predicted by using the AIJ equation.
