Solvent-based deactivator for exposed aggregate concrete with active ingredients to prevent the hydration of the top layer of the cement paste while allowing the other concrete to hydrate normally.
HEBAU’s CSE® Deactivator Pro is a water-based deactivator to achieve the desired exposure depth of exposed aggregate concrete.
HEBAU’s CSE® Deactivators are liquid, paint-like materials with active ingredient that prevent the hydration of the top layer of the cement paste in a previously defined “exposure depth”, whilst the concrete beyond this “exposure depth” hydrates normally. In this process the CSE® Deactivator only reacts with the cement paste of the fresh/green concrete in this particular depth, which leads to a neutralization.
The deactivated cement paste on the surface is then removed by “washing” with a high-pressure cleaner. The aggregates in the concrete are now exposed and therefore it is referred to as “exposed aggregate concrete” (from an exposure depth of 2 mm) resp. “micro exposed aggregate concrete” (up to an exposure depth of 2 mm).
CSE® Deactivator is available in 4 different versions and each version offers 11 different exposure-depth types.
For both, negative and positive applications:
Only for positive applications:
