FTIR spectroscopic investigation of alkali-activated fly ash: Atest study
Zaštita Materijala, 2018 Fly ash is byproduct of thermal power plants. Millions tons of fly ash is produced globally. Fly ash is disposed partly in landfills but it could also be released into the atmosphere in the past.

Contributions to the Theory of Asymptotically Sectional Hyperbolic Flows [PDF]
arXiv, 2022 In this paper, we make several contributions to the theory of asymptotically sectional-hyperbolic (ASH) flows. First, we prove that every star ASH attractor for a $C^2$ vector field is, in fact, sectional-hyperbolic (SH). Second, we establish that all ASH attractors exhibit the property of entropy flexibility.

CZECH FLUID SULFOCALCIC ASH AND FLY ASH [PDF]
Ceramics - Silikaty, 2016 Sulfocalcic ash is formed during the fluidized bed combustion of coal in the presence of limestone. It differs from classical fly ash by its composition and properties. Sulfocalcic ash contains free CaO, CaSO₄ and partially sintered aluminosilicates. In contact with water, it produces Ca(OH)₂, expansive ettringite and a small amount of the CSH phase ...

Ferrous Metal Matrix Composites Status Scope and Challenges [PDF]
arXiv, 2022 The present paper is an effort to culminate the status, scopes and challenges in the development of ferrous metal matrix composites (FMMCs). The FMMCs are old but less in use than the non-ferrous metal matrix composites (NFMMCs), as far as literature and actual applications are concerned. Therefore, this stimulates the exploration of the reasons behind

Evaluation of Fly Ash Concrete Durability Containing Class II Durability Aggregates, July 1986 [PDF]
, 1986 Fly ash was used in this evaluation study to replace 15% of the cement in Class C-3 concrete paving mixes. One Class "c" ash from Iowa approved sources was examined in each mix.

Advanced Energy and Sustainability Research, EarlyView.A highly efficient e‐CO2RR platform for efficient and selective CO production from the electroreduction of the low‐concentration CO2 in the simulated biogas is successfully established. This platform is created for the first time using geopolymer‐encapsulated graphene‐supported cobalt phthalocyanine.

Fly Ashes for HVFAC Production
Procedia Engineering, 2013 AbstractDevelopment and application HVFAC in the Czech Republic is no easy task. For production HVFAC are important raw materials. especially the quality and characteristics of the ash, which is used for the production HVFAC. The article compares selected chemical and physical properties of Czech fly ashes by foreign fly ash.
