Geopolymer is an alternative cement created from the need to provide the construction market with a type of cement with reduced environmental impacts. In other words, it appears as a sustainable alternative for the production of Portland Cement because it has low carbon dioxide emissions, requires a lower energy cost in its production, values the use of waste and still has similar to and even superior properties to Portland Cement.
This material is relatively new in the Brazilian context, so much research is still being done. To learn more about the material in question, you can read the article by one of the members of the group, and which talks about the relationship between formulation, physicochemical properties and efflorescence formation of metakaolin-based geopolymers.
