Loop quantum gravity. Loop quantum gravity (LQG) is a theory that attempts to describe the quantum properties of the universe and gravity. It is also a theory of quantum spacetime because, according to general relativity, gravity is a manifestation of the geometry of spacetime. LQG is an attempt to merge quantum mechanics and general relativity.
Eco Block, ARXX, Logixx are a few along with TriTex. Cost per block is around $12 and they are 5.33 sqft and various thickness depending on your needs. So a 35x43 house would need 234 blocks and about a ton (lift) of rebar, and require roughly 33 cubic yards of concrete using an 8  core thickness.
How Much Will It Cost? The Keystone blocks cost anywhere from $5 - $20 a square foot, depending on the blockâs style and texture. Installation fees can add about $5 - $10 per square foot. There are a wide range of shapes, sizes, textures and colors to choose from, so design options are almost endless.
