Concrete surface retarders
Concrete additives containing cement-retarding materials and other rheology control components. Controlled penetration allows the concrete to harden at the usual speed. Subsequently (even the same day or the next day), depending on the environmental conditions and requirements, the surfaces can be brushed or washed leaving the aggregate exposed on the surface, but firmly adhered to the concrete.
Obtaining aggregate relief on concrete surfaces:
- Good operation at high temperatures.
- Available in several types depending on the depth of relief to be obtained.
- They do not need the application of previous release agent.
