Fly ash

According to the morphology of fly ash particles, they can be divided into: glass microspheres; Sponge like vitreous body (including vitreous bodies with smaller, denser, and smaller pores, as well as vitreous bodies with larger, looser, and more porous particles); Charcoal particles. By grinding treatment, the original morphology and structure of fly ash are destroyed, making it a broken polyhedron with relatively uniform particle size, increasing its specific surface area, thereby enhancing its surface activity and improving its performance differences. Fly ash can be used as an admixture of cement, mortar and concrete, and become a component of cement and concrete. Fly ash can be used as a raw material to replace clay to produce raw materials for cement clinker, manufacture sintered bricks, autoclaved aerated concrete, foam concrete, hollow bricks, sintered or non sintered ceramsite, and pave roads; Constructing dam bodies, building ports, filling low-lying farmland pits, coal mine subsidence areas, and mines; It is also possible to sort useful substances such as floating beads, microbeads, iron concentrate powder, carbon, aluminum, etc. Among them, floating beads and microbeads can be used as insulation materials, refractory materials, plastics, rubber fillers, etc. respectively.
