It is not papercrete, it is regular motar mix. The one downsize is that it does not have great insulation properties but being near the equator, this is not as big of an issue. They don't have the thermal mass that retains the heat so the buildings are always cool and comfortable. With all the steel wire and mesh the walls are incredibly strong. Thank you for viewing and for your questions.
As a retired Ferrocement boat man, I see ferro concrete here, Ferrocement is made using fine sharp sand in a 2 -1 mix after 15% of the sand has been replaced with a Pozzolan like DE or Fly ash. I also add a few grams of trioxide to counter the galvanic reaction between the wet mortar and wire mesh, which causes gas bubble to form in plaster, not wanted in a boat hull. Ferrocement is water tight and requires no sealing, in fact better if allowed to breathe, for this reason we only use acrylic paint on inside of hulls..ferro concrete as used here will be porous and need a seal coat. when learning trade, the word " concrete " was never used, a clip around the ear or curses followed such slip of tongue..Ferrocement is about microns, grain size & is definitely NOT concrete..the pozzolan make the diff, the Romans idea, after Pompey, lots of ash about..
ok, so you are sayin that for ferro boats the fly ash micro size particles help make it water proof? Ive seen them using fly ash for strength in concrete.... As in 8000 plus psi vs 4000 for regular concrete..... ( im curious about ferrocement boats ..and well all boat building ..so i ask... tho you are long gone i guess.. sigh )
@@kpopandotherplaylists2518 Yes, no aggregate in ferro, finest sharp sand + a pozzolan like fly ash or DE, a hot mix of 2 - 1 and a precise amount of water creates a very strong finished product, that is water tight. 2mm skim coat above wire ensures no cracking, if thicker, cracks will show..
So is there a reason why you can't make this a monolithic build? In other words using this method to create the entire structure. Roof included? Thanks
no. it would simply require different geometry. You would require more arches and smooth corners instead of sharp corners. You ultimately would want to keep the cement under the most compression possible
+Christian Monsod (Chronizoul) best to add things per square foot. its probably cheaper and less easy. 100 or 200 dollars for one metric tonne of cement. then you just need the metal. 100 meters of chickenwire is less than 100 dollars. you shoud try making a ferrocement tank first.
Ajitkumar Khedkar, I assume you are asking if the wall is more than 3m high. We added buttresses (pillars) every 3 to 4 meters. You can see these in the video. If there are internal walls/partitions, these two will support your wall. What country are you in?

@@perkar49 2:1 = 2 sand, 1 cement or 2 cement, 1 sand? 🤔🤷🏻♂️👍
Can you teach me your craft?
Invest in some safety glasses for that angle grinder.
Its pretty common for the disks to shatter.
Is that standard angle iron and papercrete being used? WOW..Is the strength and insulative properties enough?
Parabéns

Would this approach be cheaper than using rebars and concrete blocks?

Please do we have this in kenya?
Yes, we have done this kind of construction in Kenya!!
Maşaallah sübhanallah ☺️👍
If we constructed ferrocement wall more than 3m then which type of support is required? ?

Nice work you are doing out there, cover your skin when you stick weld to avoid burns and cancer.
what is that tiny welder?
Iti it is an older Model of a Miller welder. Here is a web link:

Very nice film. Visit ferrocementindia

No way this application would be sustainable.
