Change The Way We Build

Interesting how whenever these “miracle uses for hemp” things come up, they never discuss the amount of water required. Hemp is a thirsty plant. It would also need a huge amount of agricultural space once we start using it for reinforcement in concrete as well as clothes etc.

To my mind it makes more sense to use lantana. It’s a weed we need to clear. It needs next to no moisture to grow. It works quite well as a reinforcement material. I’m sure there’s plenty of other plant sources that could be used.

I didn’t post this as a pro-hemp thread specifically. Whether or not we use the most (globally)efficient materials and methods is a fair question.

Sorry, but it’s full of crap.

Looks like a generally bullshit website, the sort of stuff that gives green politics a bad name.

>>Since lime is the binding material, builders do not have to heat up the lime as much as a supplier would need to in the industrial creation of concrete.

I am not too sure if that is woolly thinking, poor expression, poor science or all three.

Since I now have PayPal funds that are insufficient for the monitor, I might as well buy other stuff I’ve been wanting and get the monitor by bank deposit or suchlike next week.

Apologies for Wrong Thread.

I presume he means that the CO2 emissions from the manufacture of lime are lower than for Portland cement, which is true enough, but the bit about this stuff being earthquake-proof because its three times stronger than concrete certainly seems to achieve the woolly thinking, poor expression, poor science trifecta.

It’s probably more efficient than cotton.

Hemp is an amazing plant with an amazing history of usage, it was deliberately suppressed and continues to be heavily restricted so here is no objective way to compare how beneficial it could be were it allowed to be openly developed.

Hemp and bamboo have built entire nations.

It wouldn’t be too hard to be vastly more earthquake proof than concrete would it?

I don’t think hempcrete is actually a structural product, it’s merely a cladding and insulator iirc, so the building would have to be timber or steel framed.

Yep, it’s not structural so they shouldn’t be comparing hempcrete to concrete.

I only use heroincrete and methcrete when building

LOL, that reminds me of when mr Asia got busted decades ago, one paper showed his mansion and had the heading “THIS IS THE HOUSE THAT SMACK BUILT”.

That is the single most memorable newspaper heading for me.
