The Decarbonization of Construction-How Can Alkali-Activated Materials Contribute?
in Engineering
| Description | As far as structural strength of 3D-printed concrete is concerned, manufacturing defects having size lower than about 1/2 mm can be neglected, with this resulting just in a little loss of accuracy. |
| Exploitation Route | This finding can positively influenced the way the technologies to 3D-print concrete can further developed. |
| Sectors | Construction,Manufacturing, including Industrial Biotechology |
| Description | As far as structural integrity is concerned, our findings can be used by engineers to assess the detrimental effect of manufacturing defects in 3D-printed components of concrete. |

| Title | Bespoke experimental set-up |
| Description | We have developed a specific experimental set-up suitable for testing plain and notched concrete under symmetrical and anti-symmetrical bending. Tests can be run at different loading rates and the local displacements in the critical region can directly be measured using a high-speed Digital Image Correlation (DIC) camera. |
| Type Of Material | Improvements to research infrastructure |
| Year Produced | 2019 |
| Provided To Others? | No |
| Impact | This testing set-up will allow us to assess experimentally the strength of plain and notched concrete under static/dynamic Mode I-Mixed Mode I/II loading. |
