The researcher repeated the polygonal masonry of ancient civilizations [photos and video]
The author of these lines is not only related to construction, but is also interested in ancient history, especially the technologies of ancient builders. Not everything is as simple as historians say. Most of them are far from being builders or technologists or materials scientists. Therefore, many questions are simply not seen.
One of the difficult topics in history is the question of the construction of polygonal masonry. The movement of the so-called alternative history began with these questions. Buildings with elements of polygonal masonry are found not only in South America (Peru, Bolivia). There are walls of this type in Greece, Turkey and Italy. There is an imitation of such a masonry (primitive machining), but there is a high-quality one, with curvilinear conjugation along all edges.
I believe that Peruvian buildings were built using concrete technology. Moreover, the rock of the blocks there is solid limestone, not granite (as is commonly believed). This is lime-based concrete (or with its addition). Here is a screen from the breed analysis:
I outlined my thoughts in this article: Polygonal masonry in Peru. Evidence of concrete construction technology
I am not the only supporter of this version. There are researchers who show in practice that concrete technology can achieve exactly this quality of block coupling.
An example of repeating polygonal masonry - in the video in this article
Recently, another researcher wrote to me, who also repeated the principle of polygonal masonry in practice:
The concrete base of the gazebo was built. Agree, from afar it strongly resembles the ancient Peruvian masonry in Cusco or Sacsayhuaman. On closer inspection, it is clear to a specialist that this is concrete, albeit of high quality. Moreover, with a high content of air bubbles:
The pairing quality of the blocks is high, but air bubbles spoil the ideal picture.
Similar cavities can be found in blocks of polygonal masonry in Peru (third slide) - a defect during filling or molding of masses.
Here are photos of his previous work, a miniature model, so to speak:
It can be seen that it was molded like dough into plastic bags with a support of some kind of formwork. By the way, the composition of this artificial rock is similar to donkey artificial marble.
Video review of what the researcher got and the author's story:
Another video on the author's website https://polygonalwall.ru
The author does not reveal the subtleties of the technology, but as I see, the masses are poured (molded like dough) into a plastic bag, supported by formwork. The next one is formed to the previous one (or onto it).
Well, okay, someone will say, perhaps they once built using this technology. And what can this technique give in our time? Are there any benefits, benefits, savings? Isn't it easier to make just such a masonry and then imitate the seams on the plaster:
Here, after all, an imitation of seams and such a structure needs a reinforced foundation
I see the following advantages with this new (or forgotten) technology:
1. For small architectural forms (gazebos), it is not necessary to fill in a reinforced foundation. Such polygonal masonry can be cast directly onto a sand cushion. With frost heaving of the soil, the masonry will not crack as in a monolithic unreinforced foundation. Due to such a complex interface, the blocks will compensate for deformations. And the more seams there are, the better.
I was convinced of this when laying from aerated concrete. The smaller the size of the blocks in the pallet, the less chips were formed on them during transportation and unloading.
2. The decorative surface is almost at the price of concrete. No finishing required. Exclusive and monumental appearance.
3. You can cast blocks alone (option for self-builders). There was not enough concrete on some day - you can make a smaller block.
