This study was conducted improve reduction of flexural performance cuased by using acrylic round bar. For the specimen, different fiber contents(0.2%, 0.4%)was used for recycled waste ALC and the bottom ash light weight aggregate respectively to confirm the flexural performance according to the fiber content. The result of the test showed that the specimen with 0.4% fiver content shown to have improvement of flexural performance.
