Ive been sold on Hemp building materials for decades. I was shown a 4x8 sheet of hemp and 4x8 sheet of mdf. The wood failed if you looked at it. The Hemp withstood 18 wheelers driving over it sandwiched between everything to create leverage and it never failed.
I'm not really sure what you are getting at. Plants trap carbon by making O2 out of CO2 from the air, and that is how they grow. Trees are huge carbon sinks - and the trees (as well as other plants) take the CO2 out of the air as they grow. Also why plants grow better in "high" CO2 environments. "High" being 400ppm.... 0.04% of the air is CO2. This is why all the global warming retards are insane. A gas that has gone from 0.03% of the atmosphere to 0.04% of the atmosphere is going to kill us all???? WTF are they smoking and how have they brainwashed everyone to believing this lie?
In context, water vapor is a much better "greenhouse gas", responsible for 90% or so of the trapped heat, and you can see clouds. Think clouds can be more than 0.04% of the atmosphere???
The little blurb about being green is that these hempcrete blocks are taking carbon that used to be in the air, and have "sequestered" it into blocks rather than burning it or letting it decompose in the ground - releasing CO2 and methane. Using these does not create CO2 or O2 or anything else, the manufacturing process obviously creates more CO2, but after that, these blocks seem to be inert in a house.
How does this shit stand up to compression? Can it take any load whatsoever? How does it stand up over time? How much are those walls gonna shrink over 20 years or so?
Hempcrete, papercrete may have their niche uses. But Id sure be wary of buying a house made of this stuff.
It seems like a faddish sort of material. There’s all this special construction you have to perform, you can’t just hire some dude that does normal construction to use this stuff. It doesnt seem practical. There are more traditional materials that are earth friendly and energy efficient.
Read the article. It answers your questions. Less brittle than concrete so no expansion joints, but also weaker, so unsuitable for foundations. It's meant for non load-bearing insulating walls. You build your frame, and put this up outside of it. Seems like more a replacement for things like plywood sheathing and insulation rather than structural use.
There's a lot of options for windows, from adding security alarms to using polycarbonate panels. Not much use if someone can easily get through your walls.
Ok fair enough. Im still not sure if it will hold up well over time. Would be nice to see if a 50 year old hempcrete house was still in good shape. Cant find one that old.
But Im not obsessed with traditional construction or anything. Im in favor of efficiency and if his makes sense in some applications, Im for it.
Don't you get it we are done, zip, dead, ka-fucking-putt in 3 years if we don't stop ~global warming~ climate change, I been saying it for the past 9 years but you racist bigots just won't listen.
...Why wouldn't I just use concrete, or bricks, or steel for that matter? None of them burn while hemp does a little, and are stronger building materials.
You'd be surprised, hemp concrete is stronger than bricks and normal concrete. Also, most homes are built primarily from wood, so hempcrete is far less flammable.
The main benefit would be r-value I assume. All the little air pockets function like insulation. It might be cheaper than concrete block as well, or it might eventually become cheaper.

That would be my guess too. In the process of the making the brick there is a lot of air spaces created, or just the air gaps in the hemp cell structure, makes it a bigger R value than concrete.
I am really waiting for all these "green" and "recycled" materials to become cheap - but they never do. Those recycled plastic bricks will probably never be economically competitive, and the recycled tires - of which there seem to be billions of them - that are shredded to make sidewalks, should all be competitive, but nope, they are always higher prices.
Probably because of the greentards that see "organic" and "recycled" as buzzwords to justify spending more.
Hempcrete was just approved for the model U.S. residential building code during a hearing 3 months ago. Overseen by the International Code Council (ICC). The material was approved as an appendix for the 2024 International Residential Code (IRC) that governs U.S. residential building codes in 49 States.
"Carbon footprint" is retardedly irrelevant and unimportant. People need to stop caring about this. Simply using the term unironically signifies compliance to the lie that carbon dioxide is a problem.
Well its enough to QR code it and to virtue signal to other idiots who also pretend to believe and thats what most important to those narrcessistic fucks.
