  Fly Ash F Morphology and Particle Surface Modification via Mechanical Activation
  Author(s): Afaf Ghais Abadi*
  
  Fly ash F had utilized in many fields, cement replacement, geopolymer, and Nano solid material with endless applications. However, due to its low reactivity, slow hydration reaction and low early strength, the usage of Fly F represented low percentage in admixtures less than 25 wt%. Properties can be modified by mechanical activation to achieve higher added value product. The activation depends on the equipment type and its particle size range of milling. The paper reviewed the milling equipment, and tested the particle size, surface properties, and chemical compositions of activated ash. Increasing in the surface area, pozzolana activity and the reduction of crystalline dense layers of fly ash F, leading to microstructure and structural variations which can be invoked to spread the ash industrial applications. ..
