Geopolymers: ceramic-like inorganic polymers
WebIn this respect, the use of waste-based geopolymers as sorbent solids can be a very good opportunity to contribute to cleaner and sustainable processes. Waste-based geopolymers can be produced with a quite low energy input, keeping the activating solution quantities at low values, and performing the reaction synthesis at room temperature, thus ... Webgranted in inorganic chemistry. High temperature techniques are no longer necessary to obtain m~terials which are ceramic- like in their structures and properties. These …
Geopolymers: ceramic-like inorganic polymers
Did you know?
WebRefractory inorganic polymers can be made at ambient temperatures and pressures. These materials include alumino-silicates or stoichiometric “geopolymers” (which convert to single phase ceramics upon heating), alkali activated cements and materials, phosphates, and other chemically bonded inorganic compounds.

WebJan 1, 2015 · Abstract. Inorganic polymers, also called geopolymers, are becoming increasingly used as ecologically-friendly substitutes for Portland cement, in waste remediation applications and as fireproof building materials. However, interesting aspects of their chemistry open up a range of less well-known possibilities such as: electronic … WebJun 25, 2024 · In general, geopolymers are defined as ceramic-like materials formed at room temperature. They are inorganic in nature and contain a aluminosilicate polymer …
WebApr 12, 2024 · Geopolymers, also called alkali-activated materials, are ceramic-like inorganic polymers made from solid aluminosilicates cross-linked with alkali metal ions. “Geopolymer concrete made from volcanic ash (rich in aluminosilicates) can be found in the Colosseum, the Pantheon and the Egyptian pyramids,” explains project coordinator Anne … WebMay 1, 2024 · Co-products (geopolymers) can also be produced using tailing eliminating or reducing the storage in tailing dams [5, 10]. Geopolymers are ceramic-like inorganic polymers produced at low temperature, usually below 100 °C, and consist of chains or networks of mineral molecules linked together by covalent bonds, in which the raw …
WebGeopolymers are inorganic aluminosilicate polymers that form solid ceramic-like materials at near ambient temperature. The geopolymer cement is produced as an alternative way to replace the Ordinary Portland Cement (OPC). This is because the production of one ton of Portland cement emits ...
