An improved terrazzo process for applying terrazzo to an existing concrete surface comprising preparing the concrete surface, applying two layers of a primer agent, applying a terrazzo layer comprising calcium sulfoaluminate (CSA) cement, white milk glass, and one or more of broken mirrored glass and colored glass, cutting the terrazzo layer, applying a concrete densifier such that the concrete densifier penetrates into at least a portion of the concrete substrate, and grinding and polishing the densified terrazzo layer.

Binders for geopolymers, which include: a) not less than 30 w % of a mixture of at least two chemically different aluminosilicates, b) not less than 20 w % of Ordinary Portland cement, and c) 8-20 w % of a mixture of calcium sulfoaluminate cement or calcium aluminate cement with a source of calcium sulfate, wherein in the mixture the weight ratio of calcium sulfate to calcium sulfoaluminate and/or calcium aluminate is between 0.08-1.5, preferably 0.3-1.1, more preferably 0.6-1.1. Also, geopolymers using such binders as well as their use in various construction methods.
