The phrase "ash slurry" is correct and usable in written English.
It can be used in contexts related to industrial processes, environmental science, or waste management where a mixture of ash and water is discussed.
Example: "The power plant uses an ash slurry to transport waste materials to the disposal site."
Alternatives: "ash mixture" or "ash suspension".
Joshi et al. [13] investigated use of lime-fly ash slurry for ground improvement application.
The addition of coarser coal bottom ash particles in finer coal fly ash improves the rheological characteristics of coal fly ash slurry suspension.
The molar regime of both the clear solution extract and unseparated fly ash slurry was adjusted to achieve the right composition for zeolite A crystallization.
(6) In order to enlarge the fly ash slurry application toward a lightweight fill, mixtures of air foam, cement and fly ash were examined.
From the above data, it can be concluded that coal fly ash slurry can be effectively utilized in civil engineering projects.
According to the research work in South Africa, backfilling shallow underground room and pillar mines with pulverized fly ash slurry could significantly improve the mine operating conditions by providing improved roof support and increased extraction ratio (Wagner and Galvin 1979).
In addition, the ability of ash slurries to infiltrate decreases with increasing ash concentration.
For example, whereas the viscosity of the silt slurries increased monotonically with concentration, the viscosity of the ash slurries decreased.
In addition, we found that, at high concentrations, the intensity of shear-thinning in the ash slurries was greater than in the silt slurries.
Finally, it is proposed that ash slurries may evolve into progressively bulked debris flows through a positive feedback between fluid density, transport capacity, and erosivity.
Measurements have been made with fly ash slurries at various concentrations (in the range 50% to 70% by mass) and relative velocities (in the range 1 to 4 m/s).
