Thank you for sharing your experience. I wonder if the problem would be that it wasn't a wrong combination of exprimental hemprcrete, but that it was just to cold for de binding to work? Maybe it would be more solid if same mix would be used in warmer themperature.
Thanks... I guess over all the experiments were definitely ruined with temperatures so it's hard to say. I still have all the blocks that didn't make the grade. An there holding up well an are intact I even left some in a chicken pen the thing I learned was that the first stage...a bit of rotting can occur after the carbonation has taken over it all goes away an a couple years on it seems fine an the reason to experiment was for cost saving, there was no major monetary gain so its possible to experiment an it could work out fine in better temperatures but at the end I think for the effort I'd just buy iso hemp binder I liked it
Great to see the different examples. We made our own binder using hydrated lime and Metakaolin. I’ve not had chance to put a render on the building and it’s dealt with rain storms and heat with no issue.
@@bramverhoeven10 i ground some off with a grinder an it didnt come back also I used a sander it also helped the places were I rendered over nothing really came through once the carbonate process happens its gone
I made them in winter I wet conditions an the mold grew faster then they could cure ....it turned out to be only cosmetic the blocks lasted years I the chicken pen an are still there
Without knowing what you used for a binder, it is hard to determine what the mistake to avoid is. I can't not make the mistake, if I do not know what the mistake was.
I find it very disturbing the blocks you say are open to a moist climate. I live in the Netherlands and there is also a most climates and I’ve got the blocks five years in stock in a very wet not dry shed. I had more breaking problems when they were dry in the summer when I transported them one or two cracked, but when it’s handled right, I wouldn’t say anything could breakwhen you support this then this building material is forever written off and the chemical industry has one again so please take the video away. It is surely a message to the producer so send it to the producers but nobody can verify your about and how you handled them. .
Thankyou for your input its appreciated, I also live in the Nederlands .The video is about not making them below 5degrees, an that experiments with the product don't always work I have had poor results with some brands ghat probably work well in warm climates. For our climate it's best to use iso hemp, the brand that works perfectly in the Nederlands I'm interested in what what your talking about with product u have used an did you make the blocks? Did you use iso hemp? An if you have some hempcrete works, I'd love to come an see it, if your interested in an interview about your work for this channel I'd be very happy to do that
Haha yes 😂 Clay wasn't in the engineering plans.... but instead I would use scim beton which is like concrete mixed with peroxide to become foam an sets hard

Once the carbonation has taken place its like a soft limestone
How much metakaolin did you use?
@@sabuneupane8739 40/60 Metakaolin/hydrated lime
@@sabuneupane8739you can use one bag to one bag of hemp an see how it goes my neighbor did an experiment like that an it worked well
@@Hempcretinglifestyle thank you
Have you tried using microsilica?
We also have some mold on the casted walls. Its difficult to get a good ventilation everywhere. Now we use some fans to get circulating
It all disappears after about a year
@robinsonbetonbouwrobbo8847 I cant wait that long. But will removed it myself..

I thought hempcrete was mold resistant? What went wrong?
@@hyrunnisa997it's all good once the drying process happens, the mold also goes one it's done
I have been considering hempcrete because it’s supposed to be mold resistant. Why do you think your blocks grew mold?
I made them in winter I wet conditions an the mold grew faster then they could cure ....it turned out to be only cosmetic the blocks lasted years I the chicken pen an are still there
The low ph of the lime binder is supposed to reduce mould, using a different binder will probably cause issues.
They actually lasted years in the garden my chickens mostly used them to get calcium
I don't know what binders you used, at what temperature you form them and how it dries but have you followed a technical approval?
What do you mean buy technical approval
Without knowing what you used for a binder, it is hard to determine what the mistake to avoid is. I can't not make the mistake, if I do not know what the mistake was.
The mistake was working with hempcrete below 5 degrees an I'm not one to bag a product that I used below 5degrees
How did your hemp block end up?
The turned out good the leftover ones have been in the weather for a couple years now an still look fine

It is like they missing one thing to make it hard like cement blocks
Yea seems so
Seems to be tricky to get right
The temperature was the main issue
You're the second little pig, the one that used straw.
Try clay bricks next time.
Haha yes 😂 Clay wasn't in the engineering plans.... but instead I would use scim beton which is like concrete mixed with peroxide to become foam an sets hard
@@Hempcretinglifestyle glasfoam bricks...🤔
@@Hempcretinglifestyle What is Scim Beton? Is it like Aircrete?
@@CharlieKelloggPilot yes its exactly aircrete
@@helengren9349that's very expensive I buying cured ones was also smart
