Nalco Water offers colloidal silica products designed for concrete admixture applications. Our colloidal silica production is known for controlled product quality, consistency, reliability and high-volume manufacturing capabilities.

Benefits of Colloidal Silica in Concrete Production

Reduces Cement Content

Reacts with calcium hydroxide to produce excess C-S-H, reducing the amount of cement used and lowering the carbon footprint.

Enhances Finish

Improves finish quality and abrasion resistance while reducing need for curing compounds.

Increases Durability

Nanoparticles fill micropores—forming a dense, lower permeable matrix that resists water, chemicals and abrasion to extend service life.

Supports Recycling

Treating recycled aggregates with colloidal silica boosts strength and reduces chloride penetration—making them viable for new mixes.

Improves Resistance and Workability

Enhances protection against water and chemical ingress, reducing corrosion and degradation risks.

Lowers Maintenance

More durable surfaces require less frequent and less intensive cleaning or repairs.
