Encapsulation Using Adapted Geopolymer Formulations Based on Foundation Industry Wastes

Lucideon has developed geopolymer formulations for diverse applications and has built the understanding to control important characteristics.

The formulation has been adapted as a potential encapsulant for nuclear wastes as reported at previous waste management conferences; ion exchange bed media and oil wastes.

This white paper details progress through work carried out in collaboration with NUVIA considering the ability to use significant levels of Foundation Industry wastes such as metallurgical slags in the form of Ground Granulated Blast Furnace Slag or combustion products from thermal power plants in the form of fly ash and the influence on properties such as oil encapsulation efficiency, processing characteristics and indicators of compliance with disposal requirements.

Early results indicate that high levels of an oil waste simulant can be encapsulated within the refined geopolymer formulations, acceptable mechanical properties are obtained, and the bodies are resistant to leaching when immersed in water.
