In addition, the activity index of glass powder increases with grinding time. Depending on the gray correlational analysis, the mass fraction of particles ranging 0–3 μm has a maximum positive effect on its activity index at early age while particles ranging 3–10 μm contribute most at later stage. As a result, 90 min is chosen as the ...
