Mechanism Grinding Aids - Mapei

The more accepted thesis is that the grinding aids act to reduce the surface energy tòrces generated on cement grains during comminution. They are constituted by polar organic compounds, which arrange their dipoles so that they saturate the charges on the newly formed particle surfaces of the clinker, reducing agglomeration (Figure 2).
