A hydrogel is any gel in which the majority of the composition is water, a microstructure that is hydrophilic.
Nano Silica Hydrogels are three dimensional networks of silica chains that attract and contain water. As the H2O is encapsulated but not chemically bound it will continue to contribute to short and long term cementitious hydration
Colloidal Silica is a universal dispersion of micro silica that offers the advantages of:
|Accelerated and long term cement dissolution.|
|Instant CSH polymerization.|
|Reduction in pore water, free alkali content and permeability.|
|Increase in resistance to chemical degradation.|
Nano silica in the colloidal silica based hydrogel manipulates the hydrated cementations matrix of concrete reducing the connectivity of pores and cracks.
