Abstract

Worldwide, extrusion-based additive construction of cementitious materials or 3D Concrete Printing (3DCP) has gained significant momentum for large-scale construction in recent years. This technology has advanced building construction across the world; however, it is rather underdeveloped in transportation infrastructure construction. This paper addresses major hurdles hindering the wider adoption of 3DCP for unreinforced/plain pipe culvert construction. More specifically, the authors investigated the load-bearing capacity of large-scale pipes under the three-edge bearing (TEB) test. Additionally, the effects of printing discontinuities or seam sections on the structural behavior of 3DCP pipes, and their site implementation considerations as culvert structures were studied in this paper. The 3DCP pipes’ mechanical properties made with commercially available material exceeded the standard requirements. The seam section location was placed between 0 and 45 degrees from left springline towards invert which indicated pipes failed at the seam section rather than springlines when offset was 20 degrees and more from the left springline. The ultimate load capacity varied with a Coefficient of Variation (COV) of 17% between all specimens that was higher than precast pipes reported by other studies illustrating the variability of 3DCP pipes structural performance. The average measured deformation was 14% lower for pipes that failed at the seam section compared to when failed at the springline. To meet other considerations, the 3DCP pipe Manning’s values and its compliance to standard practices were determined. Tongue and groove fitting was successfully 2 designed and implemented to integrate modular construction of 3DCP pipes, demonstrating the technology viability for rapid precast construction of pipe culverts.
