Colloidal Silica - Ron Blank & Associates, Inc.

ApplicationsIn an overlay system, colloidal silica reacts with and densifiescementitious and non-cementitious surfaces where silicates fail.As a curing agent, applying colloidal silica as soon as the surface iswalkable creates a more complete reaction on the surface of theslab and, thereby, a harder finished surface.As an admixture, colloidal silica is the purest pozzolanic additive,reacting more quickly and completely with the concrete to provideearly strength.
