3D printing method can produce concrete blocks that capture and store carbon dioxide

The innovative method developed by scientists at NTU Singapore allows for the production of 3D printed concrete blocks that capture and store carbon dioxide, addressing cement's significant CO2 emissions.

By directly injecting carbon dioxide and steam into the concrete mix, the 3D printing method enhances the mechanical properties, resulting in blocks that hold 36.8% more weight and are 45.3% stronger in bending.

The technique also showcases a 50% improvement in printability, indicating that the wet concrete can be molded and printed more efficiently, thereby optimizing the construction process.
