In concrete applications, colloidal silica works exceptionally well as a stabilizer, a durability enhancer, an accelerator and a strength developer. Colloidal silica produces extremely stable, bleed-free cement slurries without free water. Additionally, at lower temperatures in deep to ultra-deep well cementing applications, colloidal silica enhances early compressive strength.
