A geopolymer is a solid aluminosilicate material usually formed by alkali hydroxide or alkali silicate activation of a solid precursor such as coal fly ash, calcined clay and/or metallurgical slag. Today the primary application of geopolymer technology is in the development of reduced-CO2 construction materials as an alternative to Portland-based cements. Geopolymers: structure, processing, properties and industrial applications reviews the latest research on and applications of these highly important materials. Part one discusses the synthesis and characterisation of geopolymers

The book covers the topic of geopolymers, in particular it highlights the relationship between structural differences as a result of variations during the geopolymer synthesis and its physical and chemical properties. In particular, the book describes the optimization of the thermal properties of geopolymers by adding micro-structural modifiers such as fibres and/or fillers into the geopolymer matrix. The range of fibres and fillers used in geopolymers, their impact on the microstructure and thermal properties is described in great detail.

This book investigates geopolymers and geopolymer-based composites, with a focus on their preparation, geopolymerization mechanisms, microstructures, mechanical properties, and fracture behaviors. Geopolymers are inorganic materials consisting of tetrahedral units (such as [SiO4] and [AlO4]) linked by shared oxygens and forming long-range, covalently bonded and amorphous frameworks. Geopolymers have the advantages of low-temperature preparation, low cost, high heat and corrosion resistance, and being environmentally friendly. Using the preparation methods for epoxy-based composite, they can easily be formed into complex shapes or

Geopolymers are a new class of binder materials and are generally classified as pure inorganic geopolymers and organic containing geopolymers. Geopolymers are multi-functional materials with applications in a large variety of scientific and industrial disciplines. Significant advancements have been made in the recent years regarding tuning of structures to meet the required set of properties so as to achieve specific applications. In this respect, the book aims to summarize synthesis, properties and applications of various advanced geopolymer systems. The wealth

Geopolymers are applied to material classes that are chemically transformed from low crystallinity aluminusilicates to three-dimensional inorganic polymers (tectosilicates). The resulting material has properties similar to natural minerals, so it is called artificial rock. However, these materials exhibit a chemical composition and mineralogical structure similar to feldspar, feldspathoidal, and zeolites consisting of a polymeric Si–O– Al framework, with a microcrystalline or an amorphous structure. Although geopolymers have attractive engineering and environmental characteristics, there are some challenges in commercializing these

When constructing wells ranging from simple land wells to complex deepwater wells, incompatibility between oil-based and synthetic-based muds (OBM / SBM) and Portland cements can lead to poor cementation and loss of cement integrity, which in turn may compromise zonal isolation. An alternative cementitious material based on geopolymers has been developed with improved OBM / SBM compatibility for primary cementing and lost circulation control as well as well abandonment. Benefits of using geopolymers go beyond mere OBM / SBM compatibility: it is in

Geopolymers are new binding material made from mostly waste material by activating with an alkaline solution. This material has high early strength, excellent durability in acids and sulphates and also reported to be highly resistant to elevated temperatures. It is considered to be an alternative to portland cement binders. Geopolymer has, of late attracted a lot of attention from civil engineers and material scientists as well. With further research, this material can be expected to revolutionize the construction industry in

Geopolymer can be synthesized using industrial wastes such as fly ash, making it a promising material to replace Ordinary Portland Cement (OPC) as a green binder for concretes. In this study, four locally available fly ashes were used to synthesize geopolymers. These fly ashes were carefully selected to include both the high calcium and low calcium fly ashes. Two of the fly ashes have very similar chemical compositions. Comprehensive experimental programs have been carried out to characterize these fly ashes,
