Can ion chromatography be used to determine the presence of DRYCRETE Products like conventional silicates?
NO, because DRYCRETE Products are not in the same category as sodium, potassium, and lithium silicates that precipitate out of solution. DRYCRETE Products revolve around a catalyzed colloidal silicate that forms reactive colloidal silica within the capillaries and pores, which is substantially different.
Conventional silicate sealers are known to contribute to concrete deterioration if they are subjected to repeated wetting / drying cycles (i.e. – exterior concrete, floor cleaning, etc.). In addition to any unreacted conventional silicate solution that is trapped within the pore space, the ionic salts that are used to stabilize the sealers’ chemistry also form compounds within the concrete porosity that are moisture sensitive and can create expansive forces. Eventually, this results in a type of craze cracking on the concrete surface. Continued wetting / drying cycles eventually lead to surface pitting and shallow potholes.
Ion chromatography is used to identify conventional silicate-based concrete surface hardeners, but it does not look for silicates per se. Instead, it looks for the ionic salts associated with their chemistry (i.e. – sodium, potassium, lithium, etc.)
Since DRYCRETE Products are based on catalyzed colloidal silicates that contain little to no ionic salts to stabilize its chemistry, the lab testing does not reveal much of anything.
