At submicron levels (less than 1 um - colloidal silica) it tends to lock up a mix and render it unworkable in high dosages. Cement is about 325 mesh or about 45 microns. Please pardon the generalizations. It's kind of neat when you think about it: Amorphous silica both causes and prevents alkali silica reactivity.

This can create ionized forms of silica or dissolved silicon dimers. So, reactive silica is a non-polymeric type of silica. The other type of silica in water supplies is colloidal silica. This occurs when silica particles are suspended in the liquid. The silica is typically spherical particles that are non-porous and amorphous.

In fact, if one uses a conventional definition of colloidal silica as that which measures greater than 50 angstroms, even ultrafiltration with a molecular-weight cutoff (MWCO) of 100,000 daltons is effective at removing colloidal silica. The RO also helps the ion-exchange process by alleviating the overall silica loading on the resin.
