Recently, the interest in digital fabrication techniques, such as 3D concrete printing, has grown at a dizzying speed, but at the same time many critical issues are still wide-open. Weak strength at the bond interface of two concrete layers, also referred as cold joint, is one such critical task to be scientifically investigated, especially in dependence on waiting time parameter between layers. It is a topic very structural engineering sensitive, because of the loss of instability and durability due to the occurrence of interface failure.
