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 ...

Comparative Toxicity of Fly Ash: An In Vitro Study
Molecules, 2021 Fly ash produced during coal combustion is one of the major sources of air and water pollution, but the data on the impact of micrometer-size fly ash particles on human cells is still incomplete. Fly ash samples were collected from several electric power

Effects of Fineness and Dosage of Fly Ash on the Fracture Properties and Strength of Concrete
Applied Sciences, 2019 This study focuses on evaluating the effects of the fineness of fly ash on the strength, fracture toughness, and fracture resistance of concrete. Three fineness levels of fly ash that respectively pass sieves—no. 175, no. 250, and no. 32—were

Farmers’ Protests in Germany: Media Coverage and Types of Bias
Agribusiness, EarlyView.ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.
