I was reading the topics and comments on the Forum and there are a lot of discussions about plastic bricks, lego houses and so on. Because I am supposed to begin some tests making bricks with PET powder, I decided to write a new topic for this subject. The bricks are not 100% plastic because it should be very resistant to be a house’s structure.
I would like to know if someone has already started this tests or projects building houses with these bricks. Let’s share ideas, “brick recipes” and molds inspirations.
If the molds work like lego toys, it would be much cheaper and sustainable. I really like this kind of bricks (https://www.facebook.com/JungleVT/videos/687153871457299/). They are wood bricks, but work pretty well.
Let’s recycle and make the difference!
Because, the mechanical properties of polymers aren’t recommended for bricks. UV will be a huge problem too.
I’ve done a research about everblock. It seems very nice and usefull.
First of all, they made thin wall pieces, what is recommended for polymers. Beside that to produce large pieces like that you will need a HUGE machine and a very expensive mold.
But the idea is excellent.
Adding UV blocker.
this text explain very well
EDIT: PET will be OK for almost a year WITHOUT any additive. If you need a higher life time you need UV blocker.
i’m no expert and I don’t want to discourage you in any way but:
1. all such materials ‘breath’, entirely useless for homes. Under no circumstance (except with extreme corruption 🙂 ) plastic bricks would get any certificate for housing. You may use it for store rooms but even that will be very limited due to chemical property (fire,..)
2. it’s unclear until which degree it can stand pressure or other loads (side forces)
3. the fact it changes rapidly under certain temperatures, limits the idea of plastic bricks even more
sorry for being a ‘brick’ 🙂
When we talk about mechanical properties for bricks we talk about compressive and flexural modulus.
PET have 3.5 and 2.7 GPa Respectivelly
Concrete without any reinforcement have 10x this values.
Another problem: Polymers expands a lot. 10x more then any metal.
Polymer are usually used as reinforcement in concrete.
Hey. I don’t know if you are still interested, but my suggestion would be to watch this video https://youtu.be/xRxB6lyMNZ8 for inspiration on your idea. in which the young man is creating paving bricks from plastics and sand to create a mixture similar to concrete.
if you are looking further to create house building bricks, it might be of help.
you may watch other videos similar to the link I have left, to gain more ideas.
@mwenzipreciousplastic-com you are exposing your self to toxic gases with bricks made of plastic. sorry mates, it’s just a bad idea ! there is a reason why people want their walls made with non-chemistry products….
