The grinding time has a linear positive correlation with the strength activity index at different curing ages, which mainly affects the later strength activity index. The number of CGS particles at 20–30 μm and 10–20 μm has the greatest impact on the early and late strength activity indexes, respectively. Therefore, considering the ...
