Achieving the high early strength of cement-based materials is a necessary condition for the rapid demolding of prefabricated buildings. In this study, kaolin treated by wet-grinding process was utilized as an accelerator in Portland cement. Wet-grinded kaolin-Portland cement system was designed, and 1–4% wet-grinded kaolin was added.
Also, the wet ability is ineffective when using polycarboxylates as a dispersant due to the poor adsorption on particle surface, leading to a decreased grinding efficiency in wet ultrafine grinding [[19], [20], [21]]. Praseodymium-doped zirconium silicate (PZS/Pr-ZrSiO 4) is widely used as a yellow ceramic pigment in ceramic industry [22].
