Utilization of coal fly ash in China: a mini-review
China is the largest coal consumer around the world, and coal accounts for more than 60% of the country’s energy mix (Peng et al. 2018; Wang et al. 2019).Coal fly ash (CFA), a solid waste produced by High calcium fly ash (HCFA) is composed of active ingredients (CaO free, aluminates and calcium silicates), which in a short time after mixing with water, participate in the hydration process and affect the rheology of concrete mixes. The higher the content of active compounds in HCFA, the higher the water demand.Fly ash and slag ScienceDirect

Synthesis and characterization of grinding aid fly ash
The amine-based grinding aid fly ash particle fineness gives 169 m 2 kg −1 higher fineness while compared to ground fly ash particles at 120 min grinding time interval [6, 33]. It is clear that grinding aid improves the specific surface area and reduce the residue when compare with GFA particles.The fly ash particles are ground from 727 cm ² /g to 3526 cm ² /g specific surface area Ground fly ash were analyzed from the Blaine's fineness test and particle size and optimized with 120 min(PDF) Investigation on grinding impact of fly ash particles
