In concrete applications, Levasil 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.
Colloidal particles interact with the free lime (calcium hydroxide) – created during cement hydration – to create calcium silicate binders. These binders produce a cohesive gel structure that enhances cement-paste density, reinforces the structure between cement grains, and eliminates free water.
When added to self-compacting concrete applications, segregation of aggregates is controlled and bleed is prevented – making the mix more stable and workable.
