Concrete retarder additives are sometimes used to reduce the impact of hot air on concrete trapping, sometimes to extend the traction time on bulky work such as large concrete dams or to pump concrete over long distances or to transport ready-mixed concrete over long distances.
Properties and effects:
- Increase concrete performance time
- Delay in concrete setting time
- Increase the strength of concrete in the long run
- Possibility of concreting in windy areas
- Possibility of concreting with long carrying distance
- Prevent surface cracks
- Possibility of concreting in tropical areas
Application:
- Massive concreting such as dam construction or very large foundations
- Concrete pumping on long distances
