Usage Areas
- In architectural applications where it is desired that the aggregates are visible on the surface in in-place poured or precast concretes (wash concrete, exposed aggregate concrete)
- It is used for roughening on fresh concrete surfaces in horizontal construction joints without the need for a physical abrasion process (sandblasting, notching, chipping, etc.). Concrete building joints roughened in this way provide significant convenience for screed and plaster applications.
- It is used to obtain applications such as walkways and terrazos with permanent visible aggregate surfaces.
Advantages
- It delays the normal hydration of cement on the concrete surface (high cement content and temperature reduce the lag). When the delay is over, the concrete continues to gain strength.
- The depth of the retarded layer depends on the amount of product applied, the time until the retardant is removed from the surface, the amount of water and cement in the mixture, and the ambient temperature.
- Reduces roughening labor costs.
- It can be diluted according to the purpose of application.
- It is easy to apply.
- It does not contain solvents.
