Experimental Study of Hardened Young's Modulus for 3D Printed Mortar.

Few studies have focused on determining the Young's modulus of 3D printed structures. This study presents the results of experimental investigations of Young's modulus of a 3D printed mortar. Specimens were prepared in four different ways to investigate possible application of different methods for 3D printed structures.

Load-Bearing Capacity of Beams Reinforced with Composite Rebar in Regard to Existing Guidelines.

Non-metallic reinforcement such as fiber-reinforced polymer (FRP) is now being increasingly used in construction. Despite numerous similarities, elements reinforced with non-metallic bars work differently from the ones reinforced with steel bars, including cracking and failure mode. The examination of the stress state in these elements, so important for their proper design, raises many difficulties.
