A distinctive benefit of lightweight aggregate concrete (LC) lies in the combination of insulating and load-bearing properties. For successful use of LC in additive manufacturing, the partly conflicting requirements on fresh material properties of the extrusion process were analyzed. One essential finding is that under pumping pressure, the density and the yield stress of LC change, leading to an improved buildability. A newly developed model including the effect of pressure on LC enables to predict buildability with less effort and higher accuracy than existing models.
