    Production of cement based composites with three dimensional polymer lattice structures and investigation of their mechanical properties
    (İdris Karagöz, 2025) Karabulut, Mehmet Yavuz; Yazıcıoğlu, Salih
    In civil engineering, concrete is the most commonly used engineering material. Despite its high compressive strength, it is weak against tensile strength and shows low ductility. Reinforcement materials are used to increase the ductility of concrete. In this study, cellular lattice structures such as Gyroid and Fluorite were embedded in cement-based mortar in order to increase ductility, provide lightness and increase energy absorption capacity. In addition, the mechanical properties of cement-based composites produced with three-dimensional polymer lattice structures were investigated using control mortar (KH), fiber mortar (LH) and Gyroid mortar (GH) and Fluorite mortar (FH) produced with two different lattice configurations. The lattice structures were produced from acrylonitrile butadiene styrene (ABS) material using 3D printers by fusion deposition modelling (EBM). Samples were prepared by embedding the lattice structures in cement-based mortar. Compression, mid-loading 3-point bending test and impact tests were performed on the produced lattice-reinforced samples. According to the results obtained; The highest compressive strength value was shown by the fiber mortar (LH) sample. It was observed that the cage-reinforced cement-based mortar samples had higher energy absorption capacity. According to the results obtained from the impact strength, it was observed that the cage-structured cement-based mortar samples showed a ductile behaviour and had higher impact absorption energy values.
