'Chrome' for Amerind Empire: Glasscrete
“In Sacagawea, the new buildings are made from concrete blocks that are slick, and smooth”
Continuing the use of broken glass as a building material, glasscrete is a mixture of concrete and ground glass (up to 80% glass). If ground to a fine powder, glasscrete can also be used as a cement replacement. Unlike conventional cement, glasscrete has a fairly smooth surface and can be polished for ornamental purposes.
