Sawdust Concrete

[@keifnoo]

I have read online that this material is great for building bird houses. And you are the only one who has a video related to it that I could find. Thank you! 👍👍

Så? 25kg cement, 70 kg sawdust 5kg water. You can not just say 25-30 percent caus it a hughe difference between weight and volume!

[@JackHawkinswrites]

Arbolite is what Google has the most specific information about with regards sawdust and either Portland cement or dehydrated lime and some ammonia sulfate. The proper amounts, etc. Hempcrete is the same, but using the hemp exclusively

Great demonstration, thank you for sharing!

[@swedishmansion8262]

Thank you

Cool great idea. R value? Type of saw dust will make a difference as well as the water content of the wood and density.

There was a Fine Homebuilding article years ago about this. The builder first tried cedar and that did not work at all. Then he used pine and that worked well. I don't know about other types of wood, but if you stick to pine, it should work for you.

Super 👍

How well does it work as a floor base? Durability and insulation would the ratios change for this

[@Not_really]

Hi, thanks for conducting this experiment. Just one question though: how does the finished material behave when submerged in water over a period of about 24 hours ? Are you able to do that for your viewers ? Thanks.

[@aliyezdi]

have you the video in English

[@hopechannelcat5462]

how much water to your mix?

[@MadebyMagnus]

Kul experiment! 👍 Skulle vara roligt att se blandningen användas till något, frågan är väl bara vad det skulle passa till.

[@swedishmansion8262]

Till hus så klart med puts på.

I've seen people add lime to protect against insects and rodents, did you add something to protect against termites?

[@swedishmansion8262]

Hi! No but I think cement will do the work

[@ullanystrom7837]

Bra

[@MrAllan9]

How will that hold up in extreme cold conditions seeing that sawdust will soak up moisture.

[@swedishmansion8262]

You must put something on. But I will test it in this winter...

[@MrAllan9]

@@swedishmansion8262 I had a similar project with paper and used a freezer to check the integrity of the test piece. Good luck.

[@swedishmansion8262]

Everything will work so you not need to go to the maffiashop and buy and buy

[@marx875]

Is it strong n light?

[@swedishmansion8262]

Very strong and light and cheap.

[@pewnis]

Med tanke på att cement inte andas särskilt bra och sågspån är ett naturmaterial så undrar jag vad som händer när sågspånet ruttnar.

[@swedishmansion8262]

Hej! Tror inte det kommer göra det. För det är ju cement runt all sågspån.

[@l0I0I0I0]

Some woods like Cypress is highly rot resistant.

[@su-mu]

What language?

[@swedishmansion8262]

Swedish

[@peace4world84]

Is lighter than concrete and sand

[@swedishmansion8262]

I`s lot lighter then sand and concrete

[@oldschoolfoil2365]

This is what china uses for concrete super structures

[@swedishmansion8262]

Yes we can save 50 procent of all forest if we build houses like this.

[@hat4et]

щепа должна быть минерализированой а сама наполненная форма должна быть провибрированна! а иначе грош цена вашему арболиту.

[@jebise1126]

ugh... why?
