Effect of fiber reinforced polymer on mechanical performance of 3D printed cementitious material

Cementitious material is mechanically brittle and weak in tensile by nature. Moreover, 3D printed cementitious material is orthotropic and have a weakness line between layers. Conventional reinforcement technique for concrete utilizes rigid rebars to impart mechanical performance of concrete stru...
