Geopolymers vs. AAM: Understanding the Crucial Differences

Get the "Geopolymer Bundle" (book + tutorial): https://www.geopolymer.org/shop/ Summary: Geopolymers are not Alkali Activated Materials (AAM). AAMs are characterized by their hydration process and are not polymers. Therefore, they cannot be called geopolymers. Geopolymers, on the other hand, are polymers and not hydrates. Consequently, the terms NASH or KASH are irrelevant because geopolymers are polymers, not hydrates. It is a significant scientific error to claim that polymers and hydrates are similar. Attempting to create a polymer using the mix design of a hydrate will result in failure (cracking, shrinkage and efflorescence). Conversely, following the kinetics of a polymer when making a geopolymer will result in success. There is no controversy. You have been misled by people who lack a proper understanding of polymers. You have been faithfully following and copying their wrong mixes and getting bad results. Everything is proven with solid scientific evidence against fake science. Video description: This video is an excerpt from a 3-hour workshop on geopolymer processing (https://www.geopolymer.org/shop). It addresses common misconceptions about geopolymer cements and explains why many attempts to produce geopolymer cements have failed to achieve the superior properties that are often cited in the scientific literature. The presenters argue that geopolymers are not alkali activated materials (AAM) and highlight the fundamental differences between the two. They emphasize the importance of understanding polymer chemistry for successful formulation. The video critiques common errors in the scientific literature, particularly those propagated between 2003 and 2019, that have led to confusion in the field. It explains why treating geopolymers as hydrates (NASH or KASH) is incorrect and provides evidence from infrared spectroscopy and the role of water to support this claim. The presenters emphasize the importance of proper terminology and understanding, pointing out that geopolymers are true mineral polymers, not hydrates or precipitates. This informative video aims to clear up misconceptions and provide a solid foundation for those interested in working with geopolymer cement, ultimately promoting a better understanding and more successful implementation of this innovative material in construction and engineering.
