We welcome you to the channel, where we, an ordinary city family, tell you how #do it yourself build #Vacation home From the foundation to the ridge of the roof. I wonder what we do? subscribe to the channel and you will see everything for yourself.
When a person just thinks about building his own home, one of the main questions he asks himself: What will I build my house from??
Fortunately, nowadays we are not limited in the choice of material. Unlike our ancestors, who were forced to build only from what is available here and now. Everything is available now. The task is not to drown in this sea of possibilities and to choose the best, the most convenient, the warmest, the most inexpensive in the end.
Perhaps today the most popular solution among self-builders is aerated concrete blocks. And not only self-builders, by the way, take a look around, almost all modern high-rise buildings are built from it. And this is not in vain: an inexpensive, warm and easy-to-work material.
But it has one drawback: with excellent thermal properties, it is rather fragile. No wonder, the slightest problems with the foundation, and the aerated concrete walls will be covered with cracks. It does not do too well as a "carrier material". Requires reinforcement belts and other "hardening".
That is why all "aerated concrete high-rise buildings" are actually not built of aerated concrete. The supporting frame of the building is usually monolithic. Aerated concrete only "fills the gaps" between the concrete columns. Excellent construction. The power function is performed by a rigid frame, while aerated concrete has only "thermal protection".
But what is good for multi-storey or industrial construction is not always applicable to an individual. The preliminary construction of a concrete frame is a rather complicated procedure and, most importantly, a lengthy one. Formwork construction, its strengthening, reinforcement binding, pouring... And then wait a long time until the concrete gains strength. There is no hurry. Before the time, props and formwork cannot be removed.
We did not build our own house from aerated concrete. Later, after finishing the walls, I discovered that there is the simplest technology of aerated concrete construction, which allows you to "turn the process inside out" and make "topsy-turvy". Not making you expect strength gain and constructing complex formwork. Combining the simplicity and low cost of aerated concrete construction and the strength of a monolithic-frame structure.
Everything is ridiculously simple: the walls themselves serve as formwork for the future concrete skeleton.
First of all, we build walls from aerated concrete blocks. Everything is as usual, but with a slight nuance: where the columns of the power frame should be located, gaps are left. Emptiness. Then, reinforcement is installed in these left voids, and the simplest formwork is built around it. And only then the concrete is poured.
And there is no need to carefully expose and level the formwork, there is no need for props and guy wires. If the walls are even, then the column will be vertical. It's so simple that even a completely inexperienced builder can handle it. Having received a completely real house with a frame made of monolithic concrete and aerated concrete filling of the enclosing structures. Durable and warm.
Warm. If you, before pouring concrete, take care of the elimination of cold bridges, for example, putting EPS sheets in the formwork. Otherwise, the columns and beams will have to be insulated later.
It is a pity that he himself did not realize such a possibility. The house would be faster and cheaper.
I wonder what disadvantages this technology has? Surely there is. What do you think? Maybe I'm wrong? Did you overlook something, but the technology is just not very successful? Will you tell?
