Fiber concrete is a technique that has been investigated for several decades, mainly to reduce the cracking problem in certain special reinforced structures. recently other applications, example, complete replacement of steel reinforcement rebars. Several structures have built without rebars by using only fiber, especially application 3D-printer technology or ultra-high performance concrete. The present paper investigates feasibility fiber rebar slabs 3D-printed individual houses. First, experiments material characterization used were performed. Then, experimental results validate numerical model. behaviour slab was evaluated model validated. showed satisfied limit states demanded houses (spans ranging 4–5 m). This result encouraging further this technology.
