Hello,
I'm trying to learn about different concrete forms and their properties. All I've come across are abbreviations without explanations and chemical formulas that I don't even hope to learn to understand.
What I'm looking for is how to create a concrete that has maximum heat capacity, doesn't create a humid indoor atmosphere if I happen to miss making a 100% perfect drainage, can hold a lot of weight, and can be sprayed onto a rebar frame.
I've spent quite a few hours trying to understand the wonder that is like liquid stone, but only more questions arise behind every answer.
For instance, I realize that the load-bearing capacity of a wall has a lot to do with the thickness and reinforcement setup. But also that the shape of the wall matters.
In my case, I'm inspired by a video on YouTube I was referred to.

Instead of a dome construction, I want to make two rebar-like constructions, two walls, which I lean against each other in an arch so that the whole thing resembles a semicircle when viewed from the side.
I've read that I also need the right fill material for the walls to support a lot of weight. But then I probably need to cast the walls for them to be weight-resistant?
Another way to reinforce, which doesn't involve boulders and rebar, is something I've read about using cellulose, plastic strips, or steel chips to create a strong construction.
Does anyone have an idea of what type of cement I should choose? What additives should I include? Can concrete be sprayed, or is it only cement that can be sprayed?
Thanks for your patience and thank you for reading all the way through.
