Geopolymer term was given by Dr Joseph Davidovits from France in 1978 and created Geopolymer Institute. Geopolymers are a class of totally inorganic, alumino-silicate based ceramics that are charge balanced by group I oxides. These are rigid gels made at lower temperature and pressure into near-net dimension bodies mostly though Vibro-casting or ramming process. One ton of Portland cement production generates 1 MT of Co2 along with enormous time savings and high chemical resistance. This material is an excellent option for the circular economy by using all kinds of ceramic, foundry and mineral wastes. Vibro Cast geopolymers have the applications in synthetic aggregates, building construction cements, road constructions, columns for building construction, waste utilization, typical shaped roof construction, park chairs construction, wall murals, sculptures for public places, statues and many more. Such Vibro Cast Products have high strength but lower productivity. Cost is the biggest challenge in the Vibro-cast or ramming process.

Work on hydraulic pressed geopolymers has been seen very low in literature survey. Hydraulically pressed geopolymers will have high strength, 3-4 times higher productivity and readymade products for infrastructure development. Laboratory scale 2-6 research work could be seen. We are working on hydraulic pressed geopolymers technology to produce these on similar pattern of Ceramic Floor Tiles Production at the baking temperature of
