An octagonal passive house in straw bales

Hey johnix, this page should interest you:

Actually, I did not know this site. It's not bad, I'm going to reference it on mine.

I still did not swallow the lime that eats the concrete ...

Lime does not eat concrete or cement. I want as proof the fact that we just mix cement and lime to make a bastard mortar.

On the other hand, it can oxidize the metal parts which are taken there. This is why one cannot "reinforce" a lime concrete in the same way as a cement concrete.

It's Belgian and it's good this link!

Blague appart, this octagonal passive house project is a very beautiful project. Very original!!!

I say congratulations for the accuracy!

Concrete is basic so it does not fear lime! Concrete craves mostly acidic compounds!
Acid rain has no damage to forests, and damage has also been reported on concrete structures.

Fully agree !!!

And for lime and steel reinforced concrete

And I do not know much slab or concrete floor that is not ARMED

From where prudence ...


Hello

[jonule]

Well, that's not prudence: do you know many slabs on which it's raining?
"ahlala these engineers they are afraid of the rain and rodents, we can do nothing more!"

otherwise thank you to you johnix for answering me, now I understand your choice!

actually straw decompressed, it leaves to think side intrusion! or can be in house mortar earth / straw / lime ...
no doubt some of the "companions" have looked into the problem ...
it is especially when it is well compressed that it is "invulnerable" ...
I learned that a layer of lime and hop more rodents! it keeps them away.

if not for the cutting of boots not necessarily rectangular, since they are attached only by 1 string, they are easily cut with the manual saw ;-)

once again hat for your initiative it will give heart to the book to + one!

Ben wish times the choices of ingest are justified ... amazing no?

ps: be careful johnix is ​​too ...

Ben you do not know the definition of a passive house (== without heating) be seen wrong ...

Here is another one in the Belgian Ardennes: https://www.econologie.com/maison-passiv ... -3537.html

I know the principle perfectly, but in the Belgian Ardennes it very rarely drops below -5 ° ... we are not in the Vosges or the Jura (where the "little French Siberia" is located ...)
Must read everything before criticizing a remark ...

[Christophe]

Ben apparently no you do not know because a passive house IS a house WITHOUT heating by definition.

As for -5 ° C, you must know better than the Ardennes their own region ...?

The -20 ° C are not uncommon ... The battle of the ardennes has also gone under temperatures of this order ...

Now it is certain that with the warming, the last 2 winters that we have spent in this region were rather "mild" (-5 ° C min) ... the one that happens seems to be already more severe (we have already had from -8 ° in November) ... but all my knowledge of the region still find it very mild (so much the better, it uses less wood).

For the Jura yes I agree but not for the Vosges ... as an Alsatian I know them well enough ...

Alsatian but not well informed, it looks like: (the -24.5 ° was in Colmar in the 80s and for 10 consecutive days: I remember it well because I had 13 ° maximum in my rental apartment type "70s" ...), because otherwise you would know that the majority of passive houses are found in the Nordic countries and in particular in Germany * and are all equipped with heating (most often by floor, wood, pellets, etc. .), certainly necessarily less powerful given the excellent insulation. The heating consumption of such a house is on average 15kw / year per square meter which is certainly not much, but far from the "0" announced a little quickly .. .
* Passiv haus: see, for example, the Vauban eco-district (site of the former French barracks) in Freiburg (Germany), ~ 30km east of Colmar and whose brand new passive houses are heated with hot water provided by a neighborhood boiler with wood chips ...)

Note that the famous house of the Belgian Ardennes was presented with many people inside, which changes many things ... and at the time of the battle of the ardennes, the Vosges lakes were frozen on 1m d ' thickness and there was more than 10m of snow on the road ridges ... all the same exceptional ....

Congratulations for this superb construction!

On the other hand, it can oxidize the metal parts which are taken there. This is why one cannot "reinforce" a lime concrete in the same way as a cement concrete.

It's funny to talk about reinforced concrete. While strolling on your site, I came across a link to another construction straw bale where the guys do the reinforcements of concrete in bamboo


Some clicks on google later I think it's fantastic as an idea!

And suddenly, more oxidation of metals with lime
Even for slabs
