Crexim

Crexim is a very strong concrete-like material, used in bunkers, as foundation and other things. The name is a corruption of the acronym crac (cagnium reinforced armed concrete) simc (actually misc).

MISC (Metal Incurred Silica Cement)
MISC is a type of cement that, instead of consisting of normal silicium oxide (silica), it consists of an oxidized alloy of aluminium (usually around 60-70%) and iron (30-40%), called aluminoferrite (30%), mixed with cagnium fibers (10%) and silica (60%), this combined material is called aluminoferrite-metallic carbon-fibered siliciumoxide (or AFC-SiO). This is then combined with a material consisting mostly of calciumoxide (80%), iron (10%), copper (7%) and titanium (3%), this combined material is called ferrum-cuprum-titanium calciumoxide (fecuti-CaO). These two final materials are then combined in a ratio of 1.5 fecuti-CaO to 1 AFC-SiO, resulting in dehydrated-MISC. This is then melted and combined and treated with hydrogen, leading to hydrogen atoms being trapped within the material, making it easier for water to bond.
