Geopolymers are a class of X-ray amorphous alkali aluminosilicate gel binder materials with potential applications in a wide range of areas. In particular, geopolymers can provide significant improvements over traditional Portland cement technology in applications requiring resistance to acid or salt attack, or thermal stability at temperatures up to 1000°C. The quasi-zeolitic nature of some of...

This paper presents the work carried out on the chemical reaction, mechanism, role of materials, applications and microstructure of fly ash geopolymer cement. Geopolymer is a type of amorphous alumino-silicate cementitious material. Geopolymer can be synthesized by polycondensation reaction of geopolymeric precursor, and alkali polysilicates. Literature demonstrates that the exact geopolymeriza...

At present, the most commonly used building material is ordinary Portland cement (OPC). However, OPC has a negative environmental effect during synthesis, with the release of significant amount of CO2 greenhouse gas. The cement industry is responsible for 5-8% of total global anthropogenic CO2 emissions. Geopolymerization is a technology capable of turning industrial wastes into strong and chem...

it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...

Currently, energy and extraction activities generate large amounts of highly polluting waste, so there is a need for sustainable environmentally friendly technologies. The aim the study to treat mining tailings fly ash through process geopolymerization. samples studied were obtained from Toquepala mine, Tacna ENGIE-Moquegua hydroelectric plant (Peru). methodology was based on two stages, first ...

Characterizing and understanding the mechanisms underlying geopolymerization are critical in achieving use of sustainable construction material, geopolymer, for widespread commercial production. Non-destructive 1 H NMR relaxometry can provide novel information about as it allows simultaneous detection where water goes how pore structure changes. Coupled with development single-sided devices, me...

The widespread use of natural aggregates is one the main causes depletion resources, as are constituents several construction materials. Alternatively, it is, today, proven to be feasible mining tailings, either or recycled materials, produce artificial through specific processes. A possible way aggregate alkali activation powdered material in a process called geopolymerization. This study prop...
