I love all of the people in the comments giving these people hell over this. Saying the concrete will leak, it will fall over, terrible work. They will probably end up putting another roofing system over the over hangs, hence the big hole in the middle. The concrete on the gables will not tip because it goes in the same amount it hangs out meaning it will balance itself. This is more than likely common practice there and im sure the other buildings are still standing. Great job guys, thanks for sharing.
Consoles like this overhang, balcony etc... MUST have reinforcement in upper zone otherwise it would break and fell off. Reinforcement ALWAYS goes on tension side. Consoles have most of the tension on the upper side, and compression on the lower side.
@@nikicamalezic5388 from a structural engineering standpoint yes, you're totally right. As you mention in multiple comments here. However as far as a vernacular architecture practice I've seen this sort of roofing done all the time in certain parts if the world. And it seems to survive just fine as long as there's not an earthquake. In seismically stable areas this practice should not work, but mysteriously it often seems to. It should be a problem, but often such roofs stand for quite some time. you're right about the lack of reinforcement and the sort of stress generated in the tension zones require much better reinforcement. The thing to remember is that engineering best practices are just that, best practices. There are structures that have existed for decades or even over a hundred years that by modern standards are dangerously under-engineered, and they still survive. At least until there is a bad earthquake. If you go to Algiers look at all the beautiful French style old apartment buildings from the early 20th century, you'll be surprised to know that a lot of those buildings, underneath the rendering, are load bearing walls literally built with rounded stones mortared together with mud. Sometimes mud and a bit of lime. Every time there's an earthquake in Algeria and some of these collapse you can see the structural detailing, it's horrendous. That said some of these buildings have been around for about a hundred years and they haven't fallen down yet..
@@romeoETmike Talking about consoles (like balcony, overhang, etc...) has one side support, other side is not supported (free) , so tension is on the upper side, and compression is on the down side. So main reinforcement must be on the upper side. And yes, with both side supported, tension is on the bottom, so main reinforcement is on the down side.
Wonderful job, I like the mini-beam/keyway placed down the middle with the stepped masonry. Avery good anchoring method. Rebar placement, damproofing and mix looks great...that'll 28 day cure pretty hard..probably 80% strength. Great job guys, keep up the good work. Watching from Birmingham, Alabama, USA!

The problem is not in the ammount of the rebar, there is more then enough, but in the basic constructional flaws. For example reinforcement MUST always be on the tension side. In consoles like this overhang tension is on the UPPER side. They putt it in the down side on the compression side. In time this will crack.
Amazing construction experts we have here in comment section. Just want to point out at 14:54 what u see is the entire part of roof wich will be casted in concrete, it is only the outer frame of the roof which stay right above the wall, so no problem with structural support strength. The central part of roof which is now open will be covered by some lightweight material. By the way have u seen flat roof entirely casted in concret, nobody wonder why that can stand up to heavy weight and water? No there is no Earthquake in VN, look for it somewhere else. Some part of VN oftern hit by storm, which oftern carry away any lightweight roof, so ppl oftern write their name and phone on roof so they will get call after storm to pickup their lost roof, the rest who got money will build house with heavy and strong roof like this. It is lighweight houses, that should be aware of storm like in USA, ppl oftern dissapear with their houses after storm.
not wrong. hear in the united States our houses are essentially made from a mix of wood frame, talk bored and paper. the framing is stuffed with spun glass for insulating. One man can literal carry a single story wall by himself depending on the size of the room. mind i am talking about modern family home construction and not the old city four family flat, or the city high risers. That are more commonly made of much heavier material. Even in our coastal reigns housing is the same but we put them on fifteen to twenty foot stilts just in case. Some times it works some times it dose not.
I’m living in Europe and Asia. In France they uses woods for roof, it’s less solid than this technical. In this video you can use all your life you will not have problems
That rebar has no rust. That is the way it should be all coated. I am impressed how these men all work together . Now i will bet that roof will last longer then anything on an american home !
Hey men, look at the steel mlesh rebars ! there is only one layer (12mm i think). So ask yourself this: "what it will happen when roof will be very hot ? What the dilatation of metal will occur ?" I help you to answer: When steel rebars will be dialted by hot weather (or rectracted when cloder), the concrete will cracks (even if good mix done as i see). Now, instead of 12mm, if you reduce the diameter of the mesh but put 2 layers of mesh rebars, with spacers between each layer, linked strongly, the dilatation of top layer will be stopped by the other one layer. This roof, i think,n would cracks in the next 10 years to come. For the isolation, it is fine to make mineral isolant, but better if you let also some air with a gap between the roof and the isolant. Good luck firends.
Why ? because of structural stregth ? I dont see that, it has metal bars not few, sure it should be covered with some metal or any shielding roofing, not low quality i think, cheers !
Use a combination of steel rebars and ferrocement mesh of various grades layers strategically to cover all gaps and spaces and ELECTROSTATICALLY SPRAY a mixtture of 2 parts cement and 1 part sand or wollastonite so that the powerful electrical attractive charge will make the steel elements to attract that 2 parts cement and 1 part sand or wollastonite to ensure EVEN COVERING AND DISTRIBUTION throughout the steel rebar and ferrocement mesh of various grades that were layered strategically to cover all gaps and spaces and be evenly and perfectly coated and filled with the same mixtture of 2 parts cement and 1 part sand or wollastonite mixture.
1. Consoles/overhangs MUST have reinforcement in upper zone and sometimes also in lover zone otherwise they would crack. Tension on console is on the upper side and compression is in the down side. 2. Missing reinforcement beams on top of the walls. Overhang on lover wall would deform in time and probably crack/deform the wall 3. If you mix concrete by hand it will not have a good quality.
3. In Vietnam, there are many places where commercial concrete trucks cannot reach. We use 0.2m3 type concrete mixer, the quality of concrete is still good. The problem is that we can control the ratio of cement:sand:stone:water.
4. Many houses are built like this and no one gives a flying frick about problems youve imagined.

@@locgold9727 Portable concrete mixers are fine and can produce enough quality concrete for for building smaller objects. But workers shroud be skilled and educated.

I'm hoping the bracings are good for intraroof support; otherwise that roof will place a tremendous amound of force on the outer walls. A few cross beams would be highly advised as to hold the roof together from splitting itself apart along the walls.
The metal rebar structure makes the roof a one piece concrete slab. I don't believe it will split but it is a heavy chunk of concrete on top of those walls.
they rookies lol, What is the purpose of the concrete roof ? to carry what weight .... they just wasting money and effort. Much simpler ways to attain a aesthetic look for this kind of roof
Esos hombres si arman unos andamios y parados sobres estos no tienen necesidaqd de correr este riesgo, ni estar metidos en el concreto para que digan que buenos trabajadores
Should put a thin layer from top to bottom of cement, then add styrocrete as the middle bulk, then top it with another thin layer of cement on top.. the two thin layers would act as a sip panel to the styrocrete making a much lighter roof...
the water absorption is minimum because the slope is acute also now days there is wonderful waterproofing products and of course the construction is kind to sloppy but what do you expect
Those panels need to have concrete on the underside surface as well - they are sort of like a structural insulated panel, which we use sometimes in North America and Europe. The underside is in tension, and the upper side is in compression. Whiteout the concrete layer on the underside, it will crack like a cookie. I always wondered how they apply the underside cement - assuming they don't use shotcrete. Maybe one of the the subscribers knows. Please share.
Concrete materials are cheap but in the west labor is costly, in the deveining world both labor and these materials are cheap, as for the physics of building this way my only question would be how the outer walls are buttressed to withstand the outword force from supporting the load which is weighed so heavily from the center of this pitched roof.

why not use light weight aircrete with wire mesh? Stucco over and paint to waterproof? Aircrete provides way more insulation.
more expansive
they only cast concret the part of roof that stand right on the wall, in the center they will use lightwieght materials.
