Concrete Bridge LCA: 3D Printing vs. Precast by 2022barc063 is a document available to read on EtoBox.

This study compares the environmental impacts of precast and 3D concrete printing (3DCP) techniques for constructing a pedestrian bridge through a cradle-to-site life cycle assessment. Results indicate that while 3DCP uses less concrete overall, its higher cement content leads to greater negative environmental impacts during construction compared to precast methods. The total carbon dioxide emissions during the construction of the 3DCP bridge were found to be 80% of those from the precast bridge, highlighti
