Geopolymers: Low Energy and Environmentally Friendly

Geopolymers, which are obtained under low-energy conditions and can be considered as a green and sustainable binder alternative to cement, have become increasingly widespread over the past several decades. They possess favorable properties, including high compressive strength, fire-resistance, high durability, rapid-set time, high performance/cost ratio, reduction in CO₂ production, and ease of processing. Moreover, geopolymer technology also provides a novel way to synthesize ceramics and their composites through proper processing procedures. At present, geopolymers and related technologies have been applied in more and more fields, such as fire proof and heat resistant composites, advanced ceramics, toxic waste management, water purification etc. In order to provide an open forum for researchers from around the world to share their expertise and up-to-date progress on their activities in this field, a special symposium with the theme of “Geopolymers: Low Energy and Environmentally Friendly Ceramics and Coatings” is included as part of PACRIM15 & CICC-13. In this symposium, contributions offering a broad perspective on the topic are desired, including geopolymerization mechanisms, 3D printing and novel manufacturing methods, ceramics formation, geopolymer composites and related ceramic matrix composites, toxic metals encapsulation, upcycling of waste as raw materials, as well as other works related to the geopolymer field in general.
