Industrial pavings additives

The use of sodium silicate for the treatment of industrial pavings has allowed, for manydecades, notable technical and economic advantages.
When applied by impregnation on a concrete surface, the silicates react with calcium hydroxide, a by-product of the cement’s hydration, in order to produce hydrated calcium silicate.
These compounds form inside the cavities and micropores of the concrete, thus creating a filling, curing and sealing effect on the surface layer of the concrete. Since it does not create a surface film, the treatment is to be considered definitive and lasting as the paving itself and the consolidation effect creates a dust-proof surface. Moreover, the trend towards the use of lithium silicate-based formulations has been
The Prochin’s R&D laboratory has developed L40 lithium silicate for the coating, treatment, consolidation of concrete pavings as well as surfaces finished with dusting. The L40 lithium silicate is a colourless low viscosity inorganic liquid that guarantees optimal workability and penetration.
When applied, it penetrates the pores of the treated cement surface and it reacts with the lime normally produced in the hydration phase of the cement in order to form resistant insoluble silicates that are able to strengthen the cement structure itself, by increasing its density.
The L40 Lithium Silicate by structural nature does not create a surface film and consequently it does not originate detachments, cracks or scratches on the treated surface. Moreover it has a high resistance to UV rays that makes the material suitable both for external and internal applications. The L40 Lithium Silicate penetrates more effectively than other sodium silicates ensuring a high protection.
After the application of the formulation, irreversible and insoluble cohesions with the concrete are created, and this guarantees sufficiently short hardening times.
