Possible test methods for the examination of the leaching behaviour of a geopolymer raw material

Absztrakt

Fly ash is an industrial by-product which is deposited in high quantities worldwide, but the use as raw material for geopolymer production would be a feasible option to eliminate not only the possible environmental damages, but the extensive land usage for the deposits. In the article, various extraction methods are summarised that could be applicable to evaluate the leaching behaviour of fly ash, based on the intended final use.
