3D concrete printing for sustainable and economical construction: A comparative study
Abstrak
: Literature about 3D Concrete Printing (3DCP) examined small-printed elements or structures, while the 11 data available about printed buildings are from the market. Therefore, there is no robust answer regarding 3DCP efficiency 12 compared to other construction methods. In this research, a two-storey building was designed using five construction 13 methods: 3DCP, prefabricated modular construction, cast-in-situ reinforced concrete, cold-formed steel and hot-rolled 14 steel. The aim is to compare 3DCP to other construction techniques in terms of the construction duration, cost and CO 2 15 emissions. This study shows that excluding prefabricated modular concrete, 3DCP reduces the construction duration by 16 about 95%. 3DCP also offers the greatest cost savings and behaves similarly to cold-formed steel to produce 17 approximately 32% less CO 2 emissions. Thus, this work provides a necessary outlook on the current viability of 3DCP 18 to relevant stakeholders and industry professionals and inspires future research on 3DCP as an economical and sustainable 19 construction solution.
