The enthusiastic way you speak about concrete is fascinating. I would appreciate if you could create a youtube video on concrete shell structures that are ideal examples where differential geometry mingles with material science.
Thanks for taking the time to teach at the World of Concrete. I wasn't registered for any of your classes but many of my team members were. I only heard good things.
The foundation of knowledge in this video,… such technologies permits for limitless application. I am hoping to build a structure soon, with synthetic mixture. Tyler Ley is a leading expert on the the future of this materials method shift. I definitely enjoy your content. Keep up the good work!
This is so awesome gave me goosebumps; I am happy I found this channel like-minded people that want to innovate and push the limits of what we are capable of doing.
Would love to see a video on cellular concrete and alternate building methods such as triple layers of frp mesh embedded in a 1.5-2" layer of regular concrete , then a 8-10" layer of cellular concrete then another concrete/mesh layer making an overall composite material and any cost or material savings. Thanks!
Tyler - love ur channel. I am not too knowledgeable about concrete but interested in the topic. Question, I assume temperatures on Mars are either above boiling or below freezing point of water depending on whether they are exposed to sunlight. Can concrete cure at such temperatures ?
mike w Curing is a chemical reaction so I believe yes, it'll cure. I imagine that reaction would fluctuate quite a bit. I think this is a great question though. I wonder if the concrete would need to cure to a very high percentage of final strength before the temp hit freezing or boiling, so very quickly.
Thanks Mike, According to Wikipedia the temp on mars at the equator is around 70F. However at night it can get down to -70F. =/ The key to concrete is to reach at least 500 psi before it freezes. If you can do that then it should be good to go. You may need to insulate the concrete after you place it or put heaters around it but I think it can be done. You could also use accelerators in the mix or anti freezing admixtures. All of these are used in very cold climates now on the earth to place concrete. I really appreciate the question and the kind words. GO CONCRETE!!!
I really don't see how printing concrete in a Mars effective vacuum can cure properly since the surface boils away the moisture to vacuum and the interior of extrusion soon flash freezes. Printing concrete inside a temporary pressurized ziplock "factory bubble" seems reasonable. The heated extrusion of regolith mixed with polyethylene binder seems much more realistic in a vacuum. Manufacturing fabric and yarn from Mars basalt also seems practical.
Another construction method is a large inflatable dome or something and then put layers of spray foam over it, and then some type of concrete spray, and then a layer of dirt.
@@TylerLey One other thing that needs to be considered is how the concrete will set-dry in places without air...so there is an advantage to rammed bags if setting is an issue. I think they tested some cement on the ISS but it wasn't a vacuum, but I can assume they tested that here on earth in a vacuum chamber.
Hello Tyler, I am curious about the mix design that was obtained from a "supplier". Do you have any idea what the mix design entailed? What type of admixtures were included? Did it use a Type III cement? Very great video!! Thanks!! Joe DiBucci
Thanks so much! I have no idea what they are using. I can tell you our mix does not use Type III cement. It is not that easy. We are controlling the aggregates, binders, and admixtures. Everything is off the shelf. We just need a little more data.
There is Somthing Right about the organic forms that are being produced when 3D printing concrete. When this method of building develops techniques for waterproofness and insulation all in one build process maybe human kind can move on from damp/cold or overly hot and expensive current building methods.
To much problem related to 3d printing...it's very hard to obtain a concrete with very specific characterics consistently. We have to manage the introduction of element resisting in tension. We need rules and codes to design with this method
Perhaps a little more concrete science, how can that many layers be put on top of each other in a short time, is there good bonding between layers, can reinforcing fibers be added or other reinforcements be used, what are the materials on mars that can be used.
More is coming. This is not the video for those details. This video was for Aleksandra to share her story. We are coring our walls now and will get a video out on the results. I am not sure you need fibers. I think you can consolidate layers with pressure as you print and you will get good bonding. Thanks for the great questions!!!
Already ordered my new business cards. "Extraterrestrial Contractor". Love it! Thank you Mr T👍
So cool!!! Send me a pic!
Never thought a channel about concrete could be so interesting :)

3d concrete printing!! thats what i was waiting for!!!
More coming...
We have some awesome stuff going on in our lab.
@@TylerLey thanks! i cant wait!
It is awesome. I can’t wait for next video about 3d printing
More to come...

Yes that can work well. The cool thing about 3D printing is that you can do any shape you want. You can also print around the rebar.

I don't understand why this team was not chosen over the team that was awarded first place, as this solution is more practical and feasible.

...so why did the end up 2nd? To make something that complex work out on the 1st try is amazing...:)
I totally agree!!!
I think 2nd is awesome. The other team must have just had a little bit more.
Marsha was just Stronger at that moment
The glue stick must have been HUGE!!! .... was it hard to get off the build plate?
HA!!! Great question.

I don't think it will be that different than normal concrete. People just need to get some experience with it.

Thank you!
Not sure what I learned here
I guess Alexandra shoud have Ukrainian roots. Proud for her!
Thank you! I am so proud of her too. I believe she is from Poland.
