Rheology of alkali-activated materials: A review
Cement and Concrete Composites, 2021Abstract Many alkali-activated materials (AAMs) exhibit poor workability in mixing owing to great viscosity of the paste and fast setting. Chemical admixtures commonly used in Portland cement-based materials, such as rheology control additives and superplasticizers, show lower efficiency in AAM systems.

Acid degradation of alkali-activated materials [PDF]
, 2022 Acid corrosion of concrete sewerage pipes arouses both industry and academy concern in recent years due to the high cost of rehabilitation and replacement. Alkali activated materials, also named geopolymers, are recommended as potential alternative materials to Portland cement (PC)-based concrete in sewer environments due to their better resistance to ...

Chemistry and materials science of alkali-activated materials [PDF]
, 2022 Learning about the action of alkali on aluminosilicate materials (natural ones or proceeding from industrial activities) is an old ambition of the scientific community. A few of those challenges established by scientists in this field are raw materials, manipulation of reactions, properties of the precipitated products, and fields for the applications.

Immobilisation of iodide in alkali-activated materials
ChemosphereAt the Fukushima Daiichi Nuclear Power Station (FDNPS), continuous water circulation cools fuel debris, leading to the presence of radionuclides such as Sr-30, Cs-137, and I-129 in the cooling water. These radionuclides are adsorbed and co-precipitated by various materials.

Volcanic tuff as a raw material for alkali-activated materials
International Journal of Advanced Natural Sciences and Engineering Researches, 2023Currently, the use of geopolymers as cementitious materials is constantly evolving due to theirexcellent properties and efficiency, such as low CO2 emissions, high compressive strength, and lowpermeability. On the other hand, volcanic tuff can be used as a potential raw material for syntheticgeopolymers due to its reactivity, wide availability in ...

Other Potential Applications for Alkali-Activated Materials
2013The focus of this chapter is the discussion of a variety of niche applications (other than as a large-scale civil infrastructure material) in which alkali-activated binders and concretes have shown potential for commercial-scale development. The majority of these applications have not yet seen large-scale AAM utilisation, except as noted in the various
