Current applications: benefits, limitations and future prospects
Geopolymers - Precursors and properties

These cold materials have several relevant characteristics such as:

• immediate or a few hours' consolidation at room temperature, enabling them to be used as a grout or binder; mechanical properties are obtained from day one; ease of processing also makes them suitable for additive manufacturing;

• adhesion to any substrate;

• resistance to severe freeze-thaw and high-temperature conditions.

What's more, from an environmental point of view, their recyclability in new formulations is possible minimizing CO ₂ emissions by 80% compared to cement. However, we can cite limitations for the use of these materials:

• 10-50% porosity, which limits certain ceramic...
