TL;DR: Geopolymers are inorganic polymers with 3D framework structures having superior mechanical and physical properties as mentioned in this paper, which have potential applications in fire resistant fibre composites, concretes for infrastructure applications, sealants and ceramics.
Abstract: Geopolymers are inorganic polymers with 3D framework structures having superior mechanical and physical properties. This new generation of cementitious materials has potential applications in fire resistant fibre composites, concretes for infrastructure applications, sealants and ceramics. Geopolymers are environmentally friendly substitutes for Portland cement: geopolymers in many applications not only reduce greenhouse gas emissions but also consume large volumes of industrial wastes such as fly ash, mine tailings and metallurgical slag. A brief review is given of geopolymer fundamentals and technology. Coverage includes structure and preparation, raw materials and the properties, particularly mechanical properties, of geopolymers. Current and potential applications of geopolymers and their advantages are introduced and discussed. The status of the geopolymer industry and the challenges that must be overcome to achieve wide acceptance and application of these novel cements is considered. Finally...

TL;DR: In this article, the performance of chloride-contaminated reinforced GPC specimens manufactured using a blended low-calcium fly ash and slag cement is investigated by long-term monitoring of corrosion parameters such as open circuit corrosion potential, polarization resistance and Tafel slopes.

TL;DR: In this paper, a comprehensive experimental program was undertaken to analyse the structural and material characteristics of synthetic fibre reinforced geopolymer concrete and the results indicated that the macro polyolefin fibres exhibited the largest fracture energy which was likely due to high mechanical bonding and low fibre aspect ratio.

TL;DR: In this paper, the effect of alkali oxides on compressive strength, microstructure and durability of circulating fluidized bed combustion coal bottom ash (CBA) geopolymer cements (GC) was discussed.

TL;DR: In this article, the workability of a geopolymer was investigated and the negative zeta potential of fly ash was identified as assisting gel formation with the smaller the negative zero potential of the fly ash, the more gel formation and high compressive strength observed.
