Can I use bamboo instead of straw for making cob/adobe brick? Do I need to cure it first or can I just slap it onto the dirt?

No, you need to use straw.
Yes, you can use it "raw" without curing it.
When stacked it needs to dry out at a certain rate, if you stack it too fast it will collapse before it is dry enough to hold more weight.
You should also put it on a foundation of stone or block to keep it off the ground. If it makes contact with the ground, it will draw moisture up from the ground and be structurally compromised.

Can I use something else to subtitute straw? Like jute?
>>1165730
Yes.
Planer shavings, saw dust, sticks or wood shavings/chips. Horse or cow poo. Any kind of natural fiber like cotton, jute, flax, ramie, sisal, hemp, coir (coconut) or dissolved paper. Mineral fibers would do it too. Longer fibers are as a general rule, desirable because they provide tensile strength to the mix.

Maybe bamboo can be crushed or chopped into properly structured fiber material? Shave it or chop and hammer, something. I wouldn't count on it but if you are living where bamboo is very plentiful it might be worth the time to experiment on.

Shred\chip maybe. Be worth testing

Bamboo you could just stack up into walls like log cabin style with a few vertical pieces to hold them together then skim with mud like plaster on lathe.
I mean that's pretty obvious right? Does it have to be these bricks?
You can split bamboo down into tiny slivers where its pretty much like tough straw I guess.

I guess I am building a paver to walk on instead of brick. That sound like a good idea to chop it up, thanks.
