Rockcrete

Rockcrete is a common building material used across the Imperium of Man that is very similar in appearance, texture and usage to ancient Terran materials like concrete. It is created by first grinding up a variety of stone and rock types native to the world where the construction will commence. This stone mix is then combined with synthetic binding agents whose recipe is known to the Tech-priests of the Adeptus Mechanicus to produce a quick-drying slurry that can be formed into walls, roofs and flooring of considerable tensile strength and survivability. Rockcrete constructions are used on almost every technologically-advanced Imperial world for one purpose or another.
