Abstract
Disclosed is a three dimensional building element having outer shells formed from cementitious compositions having different densities. The outer shell forming the exterior portion of the building element has a density greater than the interior shell to provide structure strength. The interior shell is formed from a lower density cementitious compound to provide an interior wall portion of a structure with a smooth finished appearance. The lower density of the interior cementitious compound enables the interior shell to obtain a smooth finished appearance without the need to apply various secondary coatings such as plaster or drywall.
