A geochemical analysis revealed that the composition of the H shaped blocks from Pumapunku coincided with the andesitic sand but that also included organo-mineral binders, bat droppings, and other ingredients used to produce andesite geopolymer blocks.
seems they made their own kind of concrete

Impressive for the time but come on now, that's no Sacsayhuamán

calling this material simple concrete is a huge understatement. the polymerization in some objects is semi crystalline quality and has ferromagnetic properties. the working particle size and the conditions for manufacturing this quality of geopolymer suggests extremely precise measurements and consistent manufacturing processes as well as pressure and temperature control. these objects were produced in carefully tuned exothermic processes to cool them at various stages of production, all while assumedly being embedded in some kind of massive mold.

some of the objects in aymara predate the sacsayhuaman sites by 1500 years and appear to be crafted with a very different methodology.

Tell us your theory bro

No... the point is these ancient societies had mastery over at least some aspects of chemical science. implying they were scientific civilizations who developed many relatively advanced technologies, not the cultural meccas we always associate them with.

my working theory is that when I fucked your mom there was a cosmic event known as the big bang and everything that has happened since on earth will result in this event occurring again.

>To make their geopolymer sandstone concrete, the builders may have transported finely weathered, kaolinitized sandstone from the Kallamarka site and added foreign elements such as natron (Na2CO3) extracted from Laguna Cachi, a small lake (salar) located south of the great Salar de Uyuni, in the Altiplano (Bolivia).
>>However, the most controversial aspect of the Pumapunku site is found in puzzling smaller items made of andesitic volcanic stone. Our study demonstrates that these architectural components were fashioned with a wet-sand geopolymer molding technique. The SEM study of this gray andesite shows the presence of organic matter (it could be the geopolymer binder). We have carbon, nitrogen, and mineral elements. The existence of amorphous organic matter is very unusual, if not impossible in a volcanic stone. It was also detected in the optical thin sections studies. It is a “unicum” and supports the idea of artificial andesite geopolymer concrete. To make geopolymer andesite concrete, the builders may have transported non-consolidated volcanic tuff, which is an andesite stony material having the consistence of sand from the Cerro Khapia site, and added an organo-mineral geopolymer binder manufactured with local ingredients.

it's part of the tiwanaku site, same location as OP pic.

>Surprisingly, this study demonstrates that the Pumapunku builders mastered two geopolymer concrete methods, namely:
>a) – One in alkaline medium for the red sandstone megaliths. This technology is familiar to modern material scientists and civil engineers, and is in line with knowledge of the traditional method of producing geopolymer concrete.
>b) – The second, in acidic medium for the gray andesite structures, is based on the use of organic carboxylic acids extracted from local biomass and also the addition of guano. It has been successfully replicated in our laboratory with modern chemicals in order to test the validity of the chemical mechanisms involved in the new geopolymeric reactions.

since when do olive trees grow in Bolivia like that
Thomas Collins
it's an orchard or they're decorative, idk. olives are definitely grown there and the soil is volcanic.
