Talk:Reinforcement in concrete 3D printing

Interesting article! I made very few corrections of typos. --Andrea Macrelli (talk) 13:45, 18 June 2021 (UTC)

The article gives a general and throughout idea of how concrete can be reinforced by 3D printing. Thank you for your contribution! It would be better if you provide more specific images--HybridCFD (talk) 14:34, 18 June 2021 (UTC)


 * Thanks for the suggestion. I have tried finding images but most (all) of them are copyrighted. Will keep adding as and when I find some. --BO3064 (talk) 14:47, 18 June 2021 (UTC)

The article is complete in the content and is very well written. I fixed only some typos and punctuation issues. The article is well-referenced easy to read. --Mirko Salaris (talk) 15:11, 18 June 2021 (UTC)

Observations and suggestions for improvements
The following observations and suggestions for improvements were collected, following expert review of the article within the Science, Tecnology, Society and Wikipedia course at the Politecnico di Milano, in June 2021.

Overall there is a lack of some of the aspects that are specifically related with reinforcement in 3D printed concrete (compared to ordinary concrete), like for instance adherence.

The distinction between active and passive reinforcement is not clear and also not so obvious for non-structural-engineers so it should be better explained (and the sentence “Examples of active and passive reinforcement in 3D printed concrete are reinforcement bars and post-tensioning cables used to prestress segmental elements, respectively” needs revision). Also, this distinction does not seem to be appropriate for all types of reinforcements (are fibres passive reinforcement?)

The two pictures included in the article are very generic. Pictures that are specifically related to reinforcement in 3D printed concrete would be more useful.

The corrosion behaviour of steel reinforcements (of any kind) appears to be only mentioned (for instance for galvanised cables or external connections). More generally, the concept of durability is mentioned but not easy to understand to the average reader (for instance, why should fibres make concrete more durable?). If durability is considered important, it should be addressed in a more organised way.

The sentence “Even for non-structural elements, the use of non-structural reinforcement such as fiber reinforcement is not uncommon” is pretty awkward. I suggest to revise it. Also the word “Segway” should be checked (what does it mean?).
