Material for improving the strength of cementitious material

Abstract

A novel and stable solution that can be applied on already existing cementitious structures or mixed with the cementitious matter prior to casting, is described. This solution is a simple, stable and environmentally safe material containing a sodium silicate, a dispersing agent and water containing a polysiloxane. Structures that have this material coated thereon or mixed therewith exhibit significant resistance to water penetration and resulting corrosion of re-bar elements and spalling of the concrete.
