Abstract
Shaped articles such as tiles and panels are produced from calcium aluminate cement motars by casting in a mold with a glossy water-repellent synthetic polymer surface to yield castings with highly reflective glassy surfaces. The calcium aluminate layer need only be several mils thick with the rest of the mold volume being filled with other cementitious compositions. Color pigments may be added to the calcium aluminate slurry to yield castings with brilliant glassy colored surfaces.
