Research on the Preparation and Mechanical Properties of Solidified 3D Printed Concrete Materials

Three-dimensional (3D) printing is an innovative manufacturing process based on 3D digital models that involves layer-by-layer addition of materials. In recent years, has made good progress in the field construction, thereby leading to more stringent requirements for this study, we first compare different equipment and materials used concrete. Subsequently, mix ratio extruded cured printed concrete studied by using flow slump as main evaluation indexes. Through a universal test, influence dosages water reducer, retarder, latex powder performance (compression resistance strength) studied. Furthermore, optimum fiber reinforced determined, which axial pull-out, compression, three-point bending tests are performed elucidate peak compressive strength, load–displacement curve, mechanical properties By employing ABAQUS finite element software, shaft pulling force compression simulated analyzed determine parameters influencing bonding layers. Moreover, reducer sand–glue observed be greater than gel sodium gluconate. The testing results showed strength lower poured Meanwhile, strengths quite different.
