GPCamp 2021

The Geopolymer Camp 2021, was held on August 30th to September 1st at the Campus of the University of Picardie, in Saint-Quentin, France. You will find below the Keynote conference, the list of short communications and some photos taken during this event.

Special thanks to our sponsors:

Geosil®: Silicate binders and hardeners for geopolymeric systems

The Geosil® product line are the first aqueous silicate solutions specifically designed for geopolymerization. In addition, Woellner supplies a wide range of additives to help you achieve your desired properties.

Pyromeral Systems: High-temperature resistant composites

Pyromeral Systems develops and manufactures advanced materials and composite parts for applications requiring resistance to high temperatures or fire barrier. Our unique technologies based on innovative geopolymers are designed for continuous exposure to temperatures as high as 1000°C. They provide convenient, lightweight and durable solutions for industrial processes, motorsports and aerospace applications. Pyromeral Systems brings a smart alternative when conventional composites, metals or ceramics fail to deliver the desired performance.
