Abstract

Construction 3D printing (C3DP) is an automated technology that has the potential to reduce the construction time and cost by utilizing different types of robotic systems. Due to the absence of formwork in C3DP, potential excessive water evaporation can cause issues to the freshly-printed structures that are exposed to the ambient curing condition. Moreover, the 3D printed elements should carry the service loads in a short time after printing to provide a load-bearing capacity. Destructive and non-destructive methods are the two types of methods that are being used in the construction industry for quality monitoring. Due to the time-consuming nature of the destructive methods, non-destructive methods are preferred for quality monitoring the 3D printed concrete at early ages. This study provided a comprehensive literature review on the strength development of conventional and 3D printed concrete. It also investigated the impact of different curing conditions on the strength development of 3D printed concrete at early ages. Moreover, a new sensory method was used to develop different models for estimating the mechanical properties of the 3D printed concrete at early ages.
