Bond strength of 3D printed concrete

3D concrete printing is an innovative additive manufacturing process where the material is extruded through a nozzle to print structure layer-by-layer. In this paper, the authors investigate the possibility of improving the interface bond strength of this layer by layer construction technique. Ma...
