ABSTRACT:
New light, strong, non-shrinking cellular concrete having good thermal and acoustic insulating properties prepared by incorporating aluminum and an alkaline agent capable of producing a gas when reacted with the aluminum within an anhydrite binder, placing the mixture in a mold, and permitting it to expand to a cellular product and cure. The products are useful as building materials. The invention includes the production of building elements comprising the cellular anhydrite product as described above adhered to at least one layer of a substantially non-cellular or dense facing layer made with an anhydrite binder or sandwiched between and adhered to non-cellular facing layers both made with an anhydrite binder.
