Influence of PCE-type GA on cement hydration
2021-10-4 Before grinding, clinker and gypsum were crushed into particles less than 6 ~ 7 mm diameters. The total feed weight was 3 kg per mill and the grinding time was 30 min for each ground cement [5] . Then the GA solution was evenly and dropwisely deposited onto the surface of the mixture from a syringe, and the mixture was shaken vigorously.

Polyol-type Compounds as Clinker Grinding Aids:
2020-12-9 Organic additives are widely used as ‘grinding aids’ in a variety of dry or wet mineral milling operations. In the Portland cement industry, the functions of the grinding aid are to 1) reduce the energy required to grind the clinker to a given fineness; and 2) increase the throughput of a grinding mill at constant energy [1,2].
