Geopolymers and alkali-activated materials (AAMs) are often confused, but they differ in terms of chemistry and performance. At GPI, we produce aluminum silicate-based materials for a variety of applications. We are committed to advancing materials with enhanced functionality, resilience, and sustainability, while prioritizing safety and cost-effectiveness.
We are engaged in research, development, and production of geopolymer-based sustainable construction materials, alongside the equipment to mix and print them.
