“Plastic technology” in ancient structures

Variant of mechanical (or manual) processing of the stone in the cases shown in the photo below is not applicable, as cannot be explained. I’m not dismissing it completely. It is present on many objects (blocks) around the world. Andrey Sklyarov is very clearly shows in their photo and video reports of the expeditions. But then again, tool marks, possibly left still not strong enough, not frozen rock volume. And there may be natural rock, but not on the scale of stone processing.

From the point of view of the layman – these projections are the odd elements that somehow are not removed during processing of the stone.

The official version is the jumper that initially kept the unit, connected it with the rock, not allowing it to tip over or fall down to the bottom face. The unit was kept with several of these jumpers. Before transporting under the unit put logs, jumpers cut down and dragged a block to the place.

Another variant of the official purpose of the projections is the tongs for lifting blocks. But they are not at the center of gravity (below) and do not have a suitable thickness (when lifting they just broke off).

If to take into account that these units still izgotavlivaem geopolymeric the concrete it was, then the formwork and, perhaps, cloth, Mat, separating the formwork and rock. And so that excess liquid glass with the volume of this rock, in the mould did, and drank the odd liquid seeping through the cloth, dripping. Because the mass of rock is large enough (up to several tons), that she would put the fabric into the slot in the mould. So all and polymerized within (stiffened), fabric formwork was removed, and this ledge remained.

Between blocks did posypku of plaster to the blocks do not coalesce into a monolith, and had shifts together. This preserves the seismic resistance of the structure is not cracked. And in the presence of polygonal blocks casting – seismic resistance was much higher than the laying of the blocks.

“Plastilinovaya” sides of the block from a low of formwork or convex inside shape:
