In this study, fly ash was processed by the wet grinding process (i.e. WGFA), and the ions dissolution of wet ground fly ash was examined. Then, Portland cement-wet grinded fly ash ed concrete was designed, and the effect of wet ground fly ash on the basic performance of the ed concrete was investigated, including the wet/dry density and compressive strength.

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.
Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland
Industrial wastes consumed by the preparation of building materials is a potential method to ensure the sustainable development. In this study, lithium slag (LS), as the by-product of lithium salts production, was treated by wet grinding process to prepare micro particles and used to expedite the early hydration of Portland cement (PC).
Portland cement (the only type of cement in common use today) is manufactured in a four step process. Step 1 - Quarrying ... Bay) and the wet process (used by Milburn). The dry process uses more energy in grinding but less in the kiln, and the wet process has lower overheads than the dry process. The two processes are discussed separately below.
