Thermal Properties of Geopolymers
2009The thermal properties of metakaolin and fly ash geopolymers with comparisons to ordinary Portland cement (OPC) are reviewed. The role and presence of secondary phases and aggregates are also discussed. The chapter explores the following characteristics of geopolymers upon exposure to high temperature: thermal expansion, weight loss, thermodynamics ...

Description Thirteen peer-reviewed papers provide the latest research on geopolymer binders and their performance. Topics cover the production, characterization, and use of these binders, including durability issues. With the increasing need for sustainable binders, binder systems such as s geopolymers and related ...

Geopolymer depolymerization index
Vibrational Spectroscopy, 2016Glass-like behavior of the geopolymer samples have been investigated by determination of the influence of the geopolymerization reaction equilibrium on the types of SiO4 tetrahedra polymerization present. In order to manipulate geopolymerization reaction equilibrium, aluminum and sodium content in the samples was varied.

Cement and Concrete Research, 2017
Abstract This research explores the use of simultaneous heating and pressing techniques in order to enhance the mechanical properties of fly ash (FA) based geopolymer under relatively low temperature conditions to ensure minimum-porosity. Four effective parameters of pressing force, alkali activator/FA, duration of hot-pressing and sodium ...

Geopolymers, also referred to as Aluminosilicate Inorganic Polymers (AIP) and Alkali Activated Cement (AAC) are based on alkali soluble aluminium and silicon precursors (aluminosilicates). Structural differences and resulting properties of geopolymers can be explained by variation in the source silicon to aluminium amorphous molar ratio, alkali metal ...

Materials Today: Proceedings, 2018
Abstract Geopolymer cements are an alternative to Portland cement and concretes made from this will be be more sustainable and durable. In recent years geopolymer concrete foams are new addition. Not much research has been done on this new product.
